Question

HELP ME PLS!!!!!111

a = 6 cm, b = 9 cm, and c = 3 cm

Answer 1

b + c

Explanation:

The given figure is a trapezoid of width a. Its two leg lengths are b and b + 2c. Then using the formula for the area of a trapezoid, we get:

b + b + 2c 2b + 2c

A = ----------------- * a = ------------- = b + c

2 2

Answer 2

Option B, 72 cm^2

Explanation:

The formula for the area of a trapezoid is
`(a+b)/(2)h`, where a and b represent the two base lengths and h represents the height. In this case, the two base lengths are 9 and (9+3+3)=15. Plugging this into the equation, you get
`(9+15)/(2)\cdot6=12\cdot6=72`, or option B. Hope this helps!
