Question

A scale drawing for the floor of a rectangular office shows the floor to be 33 feet long and 24 feet wide. The business wants to increase the length of the floor by 30%. The builder recreates the scale drawing to show this change. If the scale drawing shows that 1 centimeter=6 feet, then what is the length of the floor on the new scale drawing?

A. 1.65 cm
B. 4.90 cm
C. 7.15 cm
D. 10.50 cm

Answer 1

The length of the floor increased by 30% would be 33x1.30 = 42.9 feet.

The scale is 1 cm = 6 feet.

The drawing would be:

42.9 / 6 = 7.15 cm long

The answer is C.
