Answer: 8 cm
=========================================
Work Shown:
- A = given area = 240 square cm
- b1 = one parallel base = 24 cm
- b2 = the other parallel base = 36 cm
- h = unknown height
Let's solve for h in the formula below
A = 0.5*h*(b1+b2)
240 = 0.5*h*(24+36)
240 = 0.5*60*h
240 = 30h
30h = 240
h = 240/30
h = 8
The height of the trapezium is 8 cm. This is the distance between the two parallel sides.
