Question

The area of a square floor on a scale drawing is 36 square centimeters, and the scale drawing is 1 centimeter: 5 ft. What is the area of the actual floor? What is the ratio of the area in the drawing to the actual area?

Answer 1

well, say it was 6 cm by 6cm
6 * 5 ft/cm * 6 * 5 ft/cm = 36 times 25 ft^2
when you area do scale ratio squared
when you do volume use scale ratio cubed

Answer 2

scale: 1cm = 5ft.
1cm^2 = 25ft.^2.

1. A = 36cm^2 * 25ft^2/cm^2 = 900 sq. ft.

2. Ratio = 36/900 =
