Question

A rectangular room is 32 feet by 45 feet. A scale drawing of the room has a perimeter of 15 inches. What is the length of the shorter side of the room

Answer 1

3.12

Explanation:

A rectangular room is 32 feet by 45 feet.

The Perimeter of the scale drawing of the room is 15 inches

So, the perimeter of the room

2(l+w)

2(32+45)=2(77) =154

calculate the scale factor

154/15 = 10.3 when you round it

Shorter side on-scale drawing

(Length of the shorter side of the actual room) / Scale factor

32 feet / (154 feet / 15 inches) = 3.12 when you round it
