The distance between two parallel sides of a trapezium is 15 m and its area is 480 m2. If one of the parallel sides is 20 m, then length of the other side is:
Answer & explanation
Correct answer: option 2
Area of trapezium = \(\frac{1}{2}\) × ( Sum of both parallel sides ) × Height
480 = \(\frac{1}{2}\) × ( 20 + a ) × 15
960 = ( 20 + a ) × 15
64 = 20 + a
a = 44
The correct answer is Option (2) → 44 m
