Question

a blue print for a house has a scale of 1:35 in in a wall in the blue print is 3 inches what is the length in feet

Answer 1

The answer is 8.75 feet

The ratio is 1:35. Therefore if the blueprint shows 3 inches, we need to multiply it by 35 to get the actual wall. Thus 35 * 3 inches = 105 inches. Now divide 105 inches by 12 inches per foot. It is now 105 ÷ 12 = 8.75 feet.
