Answer:
80 square units
536.6 [tex]cm^{2}[/tex]
Step-by-step explanation:
First one.
2 Trapezoids
A = [tex]\frac{(base_{1} +base_{2}) }{2}[/tex] x h
A = [tex]\frac{10 + 6}{2}[/tex] x 2
A = 16
One rectangle
A = b x h
A = 6 x 8
A = 48
Total Area = 16 + 16 + 48 = 80
Second one:
Two triangles:
A = [tex]\frac{(b)(h)}{2}[/tex]
A = [tex]\frac{10(8.66)}{2}[/tex]
A = [tex]\frac{86.6}{2}[/tex]
A = 43.3
One large rectangle
A = b x h
A = 30 x 15
A = 450
Total Area = 450 + 43.3 + 43.3 = 536.6
