Question 1.

Find the area of each of the following figures. All figures are made up of rectangles.

a.

Answer:

The area of figure 1 = 10 sq cm.

the area of figure 2 = 9 sq cm.

Explanation:

In the above-given question,

given that,

area of the figure 1 = 10 sq cm.

area = l x b.

where l = length and b = breadth.

area = 5 x 2.

area = 10.

area of the figure 2 = 9 sq cm.

area = l x b.

where l = length and b = breadth.

area = 3 x 3.

area = 9.

b.

Answer:

The area of the shaded figure = 78 sq cm.

Explanation:

In the above-given question,

given that,

area of longer rectangle = 12 sq cm.

area = l x b.

area = 3 x 4.

area = 12 sq cm.

area of smaller rectangle = 2 sq cm.

area = l x b.

area = 1 x 2.

area = 2 sq cm.

area of shaded rectangle = area of longer rectangle – area of smaller rectangle.

area of shaded rectangle = 12 – 2.

area = 10 sq cm

Question 2.

The figure below shows a small rectangle in a big rectangle. Find the area of the shaded part of the figure.

Answer:

The area of the shaded figure = 24 sq cm.

Explanation:

In the above-given question,

given that,

the area of the longer rectangle = 30 sq cm.

area = l x b.

area = 6 x 5.

area = 30 sq cm.

area of smaller rectangle = 6 sq cm.

area = l x b.

area = 3 x 2.

area = 6 sq cm.

area of shaded rectangle = area of longer rectangle – area of smaller rectangle.

area of shaded rectangle = 30 – 6.

area of shaded rectangle = 24.

Question 3.

A paper rectangle has a length of 6 inches and a width of 8 inches. A square with a side length of 3 inches was cut out of it. What is the area of the remaining paper?

Answer:

The area of the remaining paper = 25 sq in.

Explanation:

In the above-given question,

given that,

A paper rectangle has a length of 6 inches and a width of 8 inches.

A square with a side length of 3 inches was cut out of it.

area = 6 x 8 = 48.

the area of remaining paper = 25.

8 – 3 = 5.

6 – 1 = 5.

area = 5 x 5.

area = 25.

Question 4.

Tila and Evan both have paper rectangles measuring 6 cm by 9 cm. Tila cuts a 3 cm by 4 cm rectangle out of hers, and Evan cuts a 2 cm by 6 cm rectangle out of his. Tila says she has more paper left over. Evan says they have the same amount. Who is correct? Show your work below.

Answer:

Tila is correct.

Explanation:

In the above-given question,

given that,

Tila and Evan both have paper rectangles measuring 6 cm by 9 cm.

Tila cuts a 3 cm by 4 cm rectangle out of hers,

Evan cuts 2 cm by 6 cm rectangle out of his.

3 x 5 = 15.

4 x 3 = 12.

so Tila is correct.

Mary draws an 8 cm by 6 cm rectangle on her grid paper. She shades a square with a side length of 4 cm inside her rectangle. What area of the rectangle is left unshaded?

Answer:

The area of the rectangle is left unshaded = 24 sq cm.

Explanation:

In the above-given question,

given that,

area of longer rectangle = 48 sq cm.

area = l x b.

area = 8 x 6.

area = 48 sq cm.

area of smaller rectangle = 24 sq cm.

area = l x b.

area = 6 x 4.

area = 24 sq cm.

area of shaded rectangle = area of longer rectangle – area of smaller rectangle.

area of shaded rectangle = 48 – 24.

area of shaded rectangle = 24 sq cm.

Question 1.

Find the area of each of the following figures. All figures are made up of rectangles.

a.

Answer:

The area of figure 1 = 48 sq cm.

the area of figure 2 = 27 sq cm.

Explanation:

In the above-given question,

given that,

area of the figure 1 = 48 sq cm.

area = l x b.

where l = length and b = breadth.

area = 6 x 8.

area = 48.

area of the figure 2 = 27 sq cm.

area = l x b.

where l = length and b = breadth.

area = 9 x 3.

area = 27.

b.

Answer:

The area of figure 1 = 64 sq in.

the area of figure 2 = 6 sq in.

Explanation:

In the above-given question,

given that,

area of the figure 1 = 64 sq in.

area = l x b.

where l = length and b = breadth.

area = 8 x 8.

area = 64.

area of the figure 2 = 6 sq in.

area = l x b.

where l = length and b = breadth.

area = 2 x 3.

area = 6.

Question 2.

The figure below shows a small rectangle cut out of a big rectangle.

a. Label the side lengths of the unshaded region.

Answer:

The side lengths of the unshaded region is = 5 ft and 3 ft.

Explanation:

In the above-given question,

given that,

the area of the larger rectangle = 10 x 7.

area = 70 sq ft.

10 – 3 + 2 = 5.

7 – 2 + 2 = 4.

so the side lengths of the unshaded region = 5 ft and 3 ft.

b. Find the area of the shaded region.

Answer:

The area of the shaded figure = 55 sq ft.

Explanation:

In the above-given question,

given that,

area of longer rectangle = 70 sq ft.

area = l x b.

area = 10 x 7.

area = 70 sq cm.

area of smaller rectangle = 15 sq ft.

area = l x b.

area = 5 x 3.

area = 15 sq ft.

area of shaded rectangle = area of longer rectangle – area of smaller rectangle.

area of shaded rectangle = 70 – 15.

area of shaded rectangle = 55.
