Answer:

124 units squared

Step-by-step explanation:

A(parallelogram) = 8 x 10 = 80

A(semicircle) = πr²/2

however, we need to use the Pythagorean Theorem to find 'r'

r² + 6² = 8²

r² = 84-36

r² = 28

r = $\sqrt{28}$ = $\sqrt{4}$ · $\sqrt{7}$ or 2 $\sqrt{7}$

A = π(2√7)² / 2

A = 4·7π / 2

A = 14π which is approx 44

Total Area = 44 + 80 = 124
