Question

A scale drawing of a rectangle painting is 12 inches long and 8 inches tall. The actual painting is 12 feet tall. What is the scale of the drawing? What is the perimeter of the actual painting? What is the area of the actual painting?

Answer 1

x = 18

Explanation:

`(8)/(12) = (12)/(x)`

• then cross-multiply

8x = 12 * 12

8x = 144

`(8x)/(8) = (144)/(8)`

x = 18
