Answer:

123 cm^2

Explanation:

for the rectangles its

#1 5(4)=20 cm^2

#2 5(7)= 35 cm^2

#3 5(8) = 40 cm^2

for the triangles its

4(7)(.5)(2)= 28 cm^2

4(7)= 28 cm^2

I get the .5 from the triangle area formula

and since the triangles are equal I multiplied it by 2 again so the .5 cancels out.

in the end you add them all up which is 20+35+40+28 = 123 cm^2
