B) triangle with base length: 8 inches, height: 3 inches
C) circle with radius: 2 inches
D) trapezoid with base lengths: 5 inches and 3 inches, height: 4 inches

Answer 1

A) A = bh = 9(4) = 36
B) A = 1/2bh = 1/2(8)(3) = 12
C) A = πr^2 = (3.14)(4) = 12.56
D) A = h/2(b_1 + b_2) = 2(5 + 3) = 2(8) = 16
