If x = 7 units, y = 2 units, and h = 9 units, find the area of the trapezoid shown above using decomposition. A.
81 square units
B.
99 square units
C.
63 square units
D.
72 square units

A) 81 sq units

Step-by-step explanation:

Area of a trapezoid = one-half of height multiplied by the sum of the bases (the bases are the parallel sides)

the problem gives us all the values we need:

height = 9

smaller base is 'x' which is 7

larger bases is 2y+x which is 2(2)+7 = 11

A = 1/2·(9)(7+11)

= 1/2·9·18

= 9·9 which is 81 sq units

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
