The area of a trapezoid is 51 square meters.
One base is 7 meters long, and the other base is 10 meters long.
Find the height of the trapezoid.(Given the area of a trapezoid A=1/2h(b+c)
where b and c are parallel sides, h is the height of the trapezoid)
:
Write the equation like this:
h(b + c) = 51
:
Multiply 2 to get rid of the fraction, results:
h(b + c) = 2(51)
h(b + c) = 102
:
Given: b = 7, c =10, replace b and c
h(7 + 10) = 102
17h = 102
:
divide both sides by 17
h =
h = 6 meters is the height
:
:
Check this by finding the area with these values
6(7 + 10) =
6(17) =
102 = 51; confirms our solutions for h = 6
