Texas Education Agency Practice Test

What is the area of a rectangle with length 8.5 cm and width 3.2 cm?

28.0 cm^2 24.6 cm^2 27.2 cm^2 32.0 cm^2

Correct Answer:

27.2 cm^2

Explanation:

Multiplying length by width gives the area of a rectangle. So use 8.5 cm and 3.2 cm: 8.5 × 3.2 = (8.5 × 3) + (8.5 × 0.2) = 25.5 + 1.7 = 27.2. The units become cm^2, so the area is 27.2 square centimeters. If a different number appears, it would come from a decimal placement or rounding error, but the exact product is 27.2.
