Question

This is a scale drawing of

A ski chalet. The height of
the chalet in the drawing
is 7 inches. The scale that maps
the drawing to the actual chalet is 1 inch to 6.5 feet.

Answer 1

Actual height of the Chalet = 45.5 ft

Explanation:

Given:

Height of chalet in drawing = 7 inches

Scale of drawing = 1 inch : 6.5 ft

Required:

Actual height of the Chalet

SOLUTION:

Actual of height of the Chalet can be calculated using proportion as follows,

Let the actual height be x.

Thus,

1 in : 6.5 ft = 7 in : x ft

`(1)/(6.5) = (7)/(x)`

Cross multiply

`1*x = 7*6.5`

`x = 45.5 ft`

Actual height of the Chalet = 45.5 ft
