Question

The area of a trapezium-shaped field is 600 m², the distance between two parallel sides is 15m and one of the parallel sides is 20 m. Find the other parallel side.

• A. 40m
• B. 50m
• C. 60m
• D. 70m

Answer 1

The correct option is C

60m

The area of trapezium of = $\frac{1}{2}$ × (Sum of the length of the two parallel lines) × (distance between two parallel lines).

600 = $\frac{1}{2}$ (a + b) × 15

a + b = 80

b = 80 – 20 = 60m

Length of the other parallel side = 60m
