1.	one of the parallel sides of a trapezium is thrice the other the area of the trapezium is 440cm² and its height is 22cm find the length of its parallel sides
Answer» Answer: let the LENGTH of the side be 'l' area of trapezium=1/2×h×(SUM of PARALLEL SIDES ) 440=1/2×22×(3l+l) 440=11×4l 40=4l l=10cm hope this answer is helpful

Answer»

Answer:

let the LENGTH of the side be 'l'

area of trapezium=1/2×h×(SUM of PARALLEL SIDES )

440=1/2×22×(3l+l)

440=11×4l

40=4l

l=10cm
