Question

(05.01)A scale drawing of a bathroom is shown below: A rectangle is shown. The length of the rectangle is labeled 2 inches. The width of the rectangle is labeled 3.5 inches. The scale is 1 to 20. What is the area of the actual bathroom in square feet? Round your answer to the nearest whole number.

7 ft2
 19 ft2
 12 ft2
 140 ft2

Answer 1

19 ft2

Explanation:

Answer 2

First solve the actual length and width of the bathroom Let l be the length and w be the width
2 / l = 1 / 20
l = 2 (20) l = 40 in

3.5 / w = 1 / 20
w = 3.5 (20)
w = 70 in

a = lw
a = 40(70)
a = 2800 in2
a = 2800 in2 ( 1 ft2 / 144 in2)
a = 19.44 ft2
