Question

An architect has a scale drawing of an addition that is to be added to a house with a scale of 1 inch: 2 feet. If the drawing is 6 inches by 10 inches, how big is the addition to the house going to be?

A) 6 feet by 10 feet
B) 8 feet by 12 feet
C) 10 feet by 12 feet
D) 12 feet by 20 feet

Answer 1

1 inch is 2 feet. So we use this and ask: 6 inch is 6 × 2 feet which is 12 feet. We do this again with 10 inch × 2 is 20 feet.

So the answer is D. 12 feet by 20 feet.

Hope this helps.
