For trapezoid, the area = (upper base + lower base) * height / 2
So area = (12 + (2*2 + 12) ) *13 / 2 = 182
Is there a picture or diagram or something

If your trying to find out E it would be the same number as G because it's the same corner and the same wideness
Answer: 2a+3b=12
b=(12-2a)/3
5a-b=13
b= -13+5a
Step-by-step explanation:
1) 2a+3b=12
-2a -2a
3b=12-2a
/3 /3
b= (12-2a)/3
2) 5a-b=13
-5a -5a
-b=13-5a
*-1 *-1 -b= 13(-1)-5a(-1) *you'd multiply by -1 to cancel out the negative on b*
b= -13+5a
