Answer:
30 units^2
Step-by-step explanation:
The area of a trapezoid is
A = 1/2 (b1+b2)h
The scale is 2 units per line
b1 = 2 units
b2 = 8 units
h = 6 units
A = 1/2 ( 2+8) * 6
= 1/2 (10)6 = 30 units^2
Honestly i just wanted to try this question since ive never seen it but i dont rlly know if i did it right at all
I equaled GH, HI, and GI together to get y
which i got y=-2
and what i got next i feel is off since
GH, HI, and GI all equaled -11
if you kind of know how to do the question maube you could correct me from there but otherwise dont take my word for it completely
