Question

The area of a trapezium is 900cm sq find the sides of the trapezium if its parallel sides are inthe ratio 11:7 and distance between them is 20 cm

Answer 1

Answer:

Area = 900cm sq

let's ratio be '11x and 7x

1/2*height*sum of parallel side

1/2*20*7x+11x=900

10×77x =900

770x=900

x=900/770

x=1.16

11x=11×1.16=12.76

7x=7×1.16=8.12
