Question

Think of a trapezoid with b1 and b2 as the length of the bases, h as the length of the altitude, and A as the area. Find the missing parts.

b1 b2 h A
6 2 18

Answer 1

h
Area of trapezoid = ---- * (b1 + b2)
2

Here area = 18 , h=2, b1=6 and we have to find b2
2
18 = ---- * (6 + b2)
2

18 = 1 * (6 + b2)
18 - 6 = b2
12 = b2
