Question

the area of a trapezium with height 14cm is 504cmsquare. if the parallel sides are in the ratio 4.5 ,find their lengths​

Answer 1

Step-by-step explanation:

let the parallel sides are 4x,5x

area of trapezium=1/2xhx(sum of parallel sides)

504=1/2x14x(4x+5x)

504=7(9x)

504/7=9x

72=9x

x=8

so parallel sides are 4x8=32

5x8=40

Answer 2

Answer:

PLS MARK ME AS BRAINLIST.

Step-by-step explanation:

let the parallel sides are 4x,5x

area of trapezium=1/2xhx(sum of parallel sides)

504=1/2x14x(4x+5x)

504=7(9x)

504/7=9x

72=9x

x=8

so parallel sides are 4x8=32
