The height of a trapezoid is 8 centimeters and one base is 5 centimeters longer than the other base. If the
area of the trapezoid is 68 square centimeters, how long is each base?
~~~~~~~~~~~~~~~~~
Area of trapezoid = * (sum of parallel sides) * height.
68= (1/2) * (x+(x+5)) * 8
simplify
8.5*2 = 2x+5
2x= 17 - 5 = 12
x = 12/2 = 6 cm the smaller base
x + 5 = 6 + 5 = 11 the longer base.
Solved.

@Mananth, as I see, you need TWO helpers:
- one to read the problem for you,
- and the other to check after you.
