Answer:
A. 34.5 sq. units
Step-by-step explanation:
For the triangle:
base = b = 3
height = h = 2
For the square:
side = s = 3
For the trapezoid:
base 1 = B_1 = 5
base 2 = B_2 = 4
height = H = 5
The total area is the sum of the areas of the triangle, square, and trapezoid.
area of triangle = bh/2
area of square = s²
area of trapezoid = (B_1 + B_2)H/2
area = bh/2 + s² + (B_1 + B_2)H/2
area = (3)(2)/2 + (3²) + (5 + 4)(5)/2
area = 3 + 9 + 22.5
area = 34.5
