Question

05.01)A scale drawing of a living room is shown below: A rectangle is shown. The length of the rectangle is labeled 3 inches. The width of the rectangle is labeled 5.5 inches. The scale is 1 to 30. What is the area of the actual living room in square feet? Round your answer to the nearest whole number.

Answer 1

Scale = 1:30
Length = (1 x 3):(30 x 3) = 3:90 (i.e. the actual length of the living room is 90 inches = 7.5 feet)
Width = (1 x 5.5):(30 x 5.5) = 5.5:165 (i.e. the actual width of the living room is 165 inches = 13.75 feet)
Area of the actual living room = length x width = 7.5 x 13.75 = 103.125
Therefore, area is approximately 103 square feet.
