Question

Bella made a drawing of her rectangular bedroom with the scale of 1 inch = 3 feet. The drawing was 5 inches long by 4 inches wide. What are the dimensions of Bella's room? What is the actual area? Show your work.

Answer 1

Explanation:

First, change each side from inches to feet.

Note that 1 inch = 3 feet. Multiply the number of inches with 3 feet

5 x 3 = 15

4 x 3 = 12

15 feet long by 12 feet wide.

To find the area, multiply the two numbers together

15 x 12 = 180

180 inch²

Answer 2

1 inch = 3 ft

1*5 inches = 3*5 = 15 ft

1*4 inches = 3*4 = 12 ft

Area = 12*15 = 180 ft^2
