Area of a trapezoid is the average of the bases times the height. (9+4.5)/2 = 13.5/2 = 6.75. 6.75 is the average of the bases you have to multiply that number by the height so 6.75x6= 40.5cm squared. The correct answer is C.

Answer:
Step-by-step explanation:
f(x) = 2x - 3
f(-9)= 2(-9) - 3 = -18 - 3 = -21
f(-3) = 2(-3) - 1 = -6 - 1 = -7
f(1)= 2(1) - 3 = 2 - 3 = -1
Area of the rectangle: {base times height}
4cm x 8cm = 32cm^2
Area of the triangle: {base times height divided by two}
(4cm x 11cm) : 2 = 22cm^2
Total area = 22cm^2 + 32cm^2 = 54cm^2
