The polygons are similar. The area of one polygon is given. Find the area of the other polygon. 4 cm
12 cm
A = 10 cm
Area =
cm2

90 cm²

Step-by-step explanation:

Given that both triangles are similar, it follows that the ratio of their area equals the square of their corresponding sides.

Let the area of the other triangle be x. Therefore:

Cross multiply

Divide both sides by 16

90 = x

Area of the other polygon = 90 cm²
