First we will find the total measure of the second base.
Second base is extended more so that meas it will measure extended part plus the first base.
Second base = 7 + 5 = 12.
Now for the area.
A = 1/2(b1+b2)(h)
A = 1/2(7 + 12)(7)
A = 66.5
The area is 66.5 ft²
Hope this helps :)
Um.. well.
you need to isolate y. minus 28 from both sides and get -1/2y=-28x-20
divide by -1/2 which leaves you with y=14x+10. Slope is 14.
