Question

The equation for the area of a trapezoid is A equals one-half times h times the quantity of b subscript 1 plus b subscript 2 end quantity..

If A = 28, b1 = 6, and b2 = 8, what is the height of the trapezoid?

h = 2
h = 4
h = 6
h = 7

Answer 1

A = (1/2)h(b1 + b2)

Plug in A, b1, and b2 and solve for h

Answer 2

so it would be h=2?

Answer 3

28 = (1/2)(6+8)h

28 = (1/2)(14)h

28 = 7h

h = 4

Answer 4

great thanks!
