Question

The scale drawing of a rectangular room has a length of 18 inches and a width of 12 inches. If the scale for the

drawing is 1 inch = 2 1/2 feet, what is the perimeter of the actual room?

Answer 1

Explanation:

Scale factor =5/2

length=5/2×18= 45

width=5/2×12= 30

perimeter = 2(L+W)

=(45×2+30×2)

90 +60

=150 inches
