Do the rectangle first.
Area = L * W
L = 4b
W = b
Area = 4b * b
Area = 4 *3 * 3
Area = 36 square inches.
Do the trapezoid next
b1 = a
b2 = 2a
h = a
Formula
Area = (b1 + b2) * h / 2
Area = (a + 2a) * a / 2
Area = (3a) * a / 2
a = 4
Area = (3*4) * 4 / 2
Area = 12 * 4/2
Area = 48 /2
Area = 24
Total Area
Area = 24 + 36
Area = 60 in^2
B <<<< answer
