the area of the trapezoid is 9
Answer:
A = 7.5 unit^2
Step-by-step explanation:
The area of a trapezoid is found by
A =1/2 (b1+b2) *h
b1 = 1 unit
b2 = 4 units
h = 3 units
I found these by counting on the graph
A = 1/2(1+4) *3
A = 1/2(5)3
the one u clicked was the answer
x=12
3x=2x+12
-2x from each side
-12x+12
8-20x+12-4+8x-4
