Respuesta :

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

Answer:39.48cm^2

Step-by-step explanation:

8.61+22.26+8.61 = the area of the trapezoid is 39.48
