Question

A room in a house is shown on a blueprint. The blueprint has a scale of 5 inches:8 feet. A wall in the same blueprint has a length of 30 inches. What is the actual length of the wall

Answer 1

30÷5 = 6
8×6= 48 feet

Answer 2

48 feet.

Explanation:

A room in a house is shown on a blueprint.

The blueprint has a scale of 5 inches = 8 feet.

Therefore, 1 inches =
`(8)/(5)` = 1.6 feet

The length of the wall in the blueprint = 30 inches

The actual length of the wall = 30 × 1.6

= 48 feet.

The actual length of the wall is 48 feet.
