Question

What is the area, in square centimeters, of the isosceles trapezoid below?

5-3 cm
4.2 cm
13.5 cm

Answer 1

both triangles area:

4.2 x 8.2 = 34.44

you don’t need to divide by two cause there’s two triangles anyways.

also, you get 8.2 by subtracting the total length by the top length. (13.5-5.3)

rectangle:

4.2 x 5.3 = 22.26

the total area is 56.7cm squared
