Answer: 140 [tex]in^{2}[/tex]
Step-by-step explanation:
The area for a trapeziod is A = [tex]\frac{1}{2}[/tex](b1+b2)h
We have almost everything we just need the total length of the top base, since it gives us the outer lengths we can find that by simply doing 4+6+15 which turns out to be 25
Now we can plug in our values:
A = [tex]\frac{1}{2}[/tex](25 + 15) x 7 = 140[tex]in^{2}[/tex]
