Question

A scale drawing is to be made of the floor of a rectangular room whose dimensions are 40 feet by 28 feet. The scale to be used is 1 inch: 4 feet. What will the perimeter of the scale drawing be in inches?

A) 42
B) 52
C) 34
D) 80

Answer 1

The perimeter of the scale drawing will be 34 inches.

Step-by-step explanation:

To find the perimeter of the scale drawing, we need to convert the dimensions of the room into inches. The scale ratio is 1 inch:4 feet. So, for the length of 40 feet, the length in inches would be 40/4 = 10 inches. And for the width of 28 feet, the width in inches would be 28/4 = 7 inches. Now we can find the perimeter of the scale drawing by adding all four sides, which would be 2*(10+7) = 34 inches.
