Question

The area of a trapezium with height 14 cm is 504 cm^2.If the parallel sides are in the ratio 4:5, find there lengths

Answer 1

Area of trapezium =1/2(sum of parallel sides)×height

Let the parallel sides be 4x and 5x

1/2(4x+5x)×14=504

9x×7=504

9x=72

x=8

Parallel sides are 4x and 5x = 32cm and 40cm
