Question

17. A scale drawing of a pool is shown. The length of the pool in the drawing is 4.6 inches. The scale that maps the drawing to the actual

pool is 1 inch to 3.4 feet.
Using the scale given, enter the actual length, in feet, of the pool.

Answer 1

15.64 ft

Explanation:

Scale of the drawing = 1 inch to 3.4 feet

Length of pool in the drawing = 4.6 inches

Let "x" represent the actual length of the pool.

Thus,

1 inch : 3.4 ft = 4.6 inches : x ft

`(1)/(3.4) = (4.6)/(x)`

Cross multiply

`(1)(x) = (4.6)(3.4)`

`x = 15.64`

Actual length of the pool is 15.64 ft
