Answer:

Area = 546.8

Step-by-step explanation:

We can calculate the area like for a rectangle since if we take the one triangle and pop it on top, the shape becomes a rectangle, so:

Find side of triangle:

A^2 = b^2+c^2 -2acCos(a)

A^2 = 436

A= 20.9

Height : 23.2+20.9

Height: 44.1

Width: 12.4

Area = w * h

Area = 546.8
