Question

Triangle MNO is dilated by a scale factor of 7/8 to create triangle M'N'O'.

The area of triangle MNO is x square units.

What is the area in square units of triangle M'N'O'?
A. 7/8x square units
B. (7/8)^2x square units
C. (1/8)^2x square units
D. 8/7x square units

Answer 1

When dilating a figure, the area is multiplied by the square of the scale factor. In this case, the scale factor is 7/8, so the area of triangle M'N'O' is equal to (7/8)^2 times the area of triangle MNO.

Therefore, the correct answer is (B) (7/8)^2x square units.
