Question

The drawing plan for an art studio shows a rectangle that is 15.2 inches by 8 inches. The scale in the plan is 4 in.: 5 ft. Find the length and width of the actual studio. Then find the area of the actual studio. The length is feet, the width is feet, and the area is square feet.

Answer 1

Length: 19 feet

Width: 10 feet

Area: 190 feet
`x^(2)`

Explanation:

This is a question about ratio.

Length: let
`x` be the actual length.

`15.2 : x = 4 : 60`

`x = 19`

Width: let
`y` be the actual width.

`8 : y = 4 : 60`

`y = 10`

Area: A = xy

`19 * 10 = 190`
