Question

The area of a trapezium with height 14 cm is 525 cm ^ 2 . If the parallel sides are in the ratio 2 :3 , find their lengths. 20 cm and 30 cm 24 cm and 36 cm 30 cm and 45 cm 32 cm and 48 cm​

Answer 1

Answer:

Step-by-step explanation:

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
