Answer:
a. 58 in²
Explanation:
dived the figure into 3 areas (see attached image)
1. area of a triangle = 1/2 b h where b=6 , h=3
A1 = 1/2 (6) 3 = 9
2. area of trapezoid = a + b * (h/2) here a = 4, b = 6, h = 5
A2 = (4 + 6 ) * 5/2 = 25
3. area of a triangle = 1/2 b h where b=8 , h=6
A3 = 1/2 (8) 6 = 24
total area = 9 + 25 + 24
= 58 in²
