Scale Drawings and Area

Question 9 • FL-1205040-M/J Grade 7 Mathematics B -GF

A room is 12 feet long and 10.5 feet wide. A scale model of the room is 3.5 feet wide. What is the area of the scale model?

Answer
A
10.3 square feet
B
14 square feet
C
36 square feet
D
122.5 square feet

Explanation

The model’s width is 3.5 feet compared with the room’s 10.5-foot width, so each model dimension is one-third the corresponding room dimension. The model’s length is therefore 12 ÷ 3 = 4 feet. Its area is 4 × 3.5 = 14 square feet, so the correct choice is 14 square feet.
