Kierra Mcconnell · Answer 1

The formula for area of a trapezoid is 1/2h• (b+b)

so let's plug in the numbers

1/2h• (70) = 525

so divide both sides by 70

1/2h=7.5

now divide both sides by 0.5

h=15

so the height is 15.

Well for firsts the area of a trapezoid is A = (b1+b2) h * 1/2 or A = (b1+b2) h divided by 2.

So basically we have to do the opposite kind off.
