Answer:

28

Step-by-step explanation:

A = b h

b base

h height

To find height use pythagorean theorem

5^2 = 3^2 + h^2

25 = 9 + h^2

h^2 = 25 - 9

h^2 = 16

h = 4

base = 7

height = 4

Area = 7 x 4

A = 28
First you take the area of te triangles, base x height divides by two then you just take the square area
