The rectangle is being reduced by a scale factor of 3/4. What is the area of the new image?

F. 180 cm²
G. 90 cm²
H. 160 cm²
J. 75 cm²

Answer 1

The rectangle is being reduced by a scale factor of 3/4, which means each side is reduced by the scale factor of 3/4. Therefore, we have 8* (3/4) = 6, and 20* (3/4) = 15. So, the new side lengths are 6 and 15, and so the area is 90 (6x15).

Answer 2

90 cm^2

Explanation:

The side lengths are reduced by 3/4

8 * 3/4 = 6

20 * 3/4 = 15

The new side lengths are 6 cm by 15 cm

The area is

A = l * w

A = 6*15 = 90 cm^2
