Question

Two trapezoids have areas of 432 cm2 and 48 cm2. Find the similarity ratio of the sides of the trapezoids.

Answer 1

If two polygons are similar, the square of the scale factor of the two polygons is equal to the ratio of the areas of the solids.

432/48 = (scale factor)^2

(27*16) / (3*16) = (scale factor)^2

27/16 = (scale factor)^2

Take square roots of both sides to get the scale factor. @melito17
