A blueprint shows the master bedroom to be 5 inches long and 3 inches wide. The scale on the blueprint is 2 inches : 11 feet. What is the area (in sq ft) of the actual bedroom?

Answer 1

The area of the bedroom actually is 453.75 sq ft.

Explanation:

Given that,

A blueprint shows the master bedroom to be 5 inches long and 3 inches wide.

The scale on blueprint is 2 inches : 11 feet.

It means 2 inches = 11 feet.

Then,

1 inches
`=(11)/(2)` feet = 5.5 feet.

So,

The length of the bedroom is 5 inches = (5×5.5) feet=27.5 feet

The wide of the bedroom is 3 inches = (3×5.5) feet= 16.5 feet

The area of the bedroom actually is = length × wide

=(27.5×16.5) square ft

=453.75 square ft
