Question

the length of the parallel side of a Trapezium are in the ratio 4 : 7. if the height of Trapezium is 14 m and its area is 385 sq.m, find the length of its parallel sides.​

Answer 1

Step-by-step explanation:

let the parallel sides be 4x and 7x

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

》area=14×(4x+7x)/2

》385=7×11x

》11x=385/7

》x=55/11

》x=5m

》4x=20 m ans

》7x=35 m ans
