Find the area of the trapezoid.
12.2 cm
10.2 cm
12.6 cm

if height is 12.6:  A≈141.12

if height is 10.2:  A≈126.48

if height is 12.2:  A≈139.08

Step-by-step explanation:

Area = 1/2 x height x (base1 + base2).

1/4 because there is 4 grades.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
