Question

On a scale drawing with a scale of 1/20,the height of building is 8 inches how tall is the actual building in feet

Answer 1

The actual building is 13.3 feet tall.

Explanation:

Let the actual height be 'x'.

Given that on a scale drawing with a scale of 1/20, the height of the building is 8 inches, the expression becomes

(1/20) × x = 8

x = 20 × 8 = 160 inches

We know that

• 1 foot = 12 inches

Thus,

160 inches = 160/12 ≈ 13.3 feet

Therefore, the actual building is 13.3 feet tall.
