What is the area of this trapezoid a 50 in² b 108 in² c 126 in² d 192 in²

C 126 in²

Step-by-step explanation:

The area of a trapezoid is given by

A = 1/2 (b1+b2) h

b1 is the bottom base length = 12 inches

b2 is the top base length = (2+12+2) = 16 inches

h = height = 9 inches

A = 1/2 (12+16) *9

A = 1/2(28)(9)

A =126 in^2

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
