Answer:
90 cm^2
Explanation:
Divide the rectangle and square into two separate figures and add them together at the end.
Top rectangle: We know that area of a rectangle is A=lw. Here, we see that w=5 cm. For the length, we add 4+5+4=13 (5 comes from the bottom square). So A=5(13)=65
Bottom square: Area of a square is A=s^2 where s=5 in this case, so A=5^2=25
Total Area: Add together two figure's area: A=65+25=90 cm^2
