Answer:

136 cm^2

Step-by-step explanation:

The area of a trapezoid is found by

A = 1/2 (b1+b2) *h where b1 and b2 are the lengths of the bases and h is the height

A = 1/2 ( 12+22) *8

= 1/2 (34) * 8

= 136 cm^2

Let 'x' represent the length of the material in feet that you can be with $30.

(4.99/3)*x <= 30

157 degrees ... set 4x-5 = x+16 then solve, you should get x=7, plug in 7 for one of the equations and you'll get 23. subtract 23 from 180 and get 157. hope that helped :)
