Question

THE AREA OF A TRAPEZIUM IS 360 sq. m, THE DISTANCE BETWEEN TWO PARALLEL SIDES IS 40 m AND ONE OF THE PARALLEL SIDE IS 25 m. FIND THE ....

LENGTH OF THE TR PARALLEL SIDE.

​

Answer 1

Step-by-step explanation:

Given,

Area of trapezium =360m2

Distance between two parallel lines =20m

One parallel side =25m

 

Let's assume the second parallel side to be x m

∴  Area =(25+x)×20

⇒360=(25+x)×20

⇒x=36−25=11m

Therefore, the second parallel side is 11m

Answer 2

Answer:

the formula for trapezium is 1/2(sum of parallel sides) *height.

Step-by-step explanation:

given area = 360sq.m.^2

let other parallel side be x.

area of trapezium = 1/2(sum of parallel sides) *height.

360=1/2(x+25)*20

360=10*x+25

360=10x+25

360/10=x+25

x+25=36

x=36-25

x=11.

so the other parallel side is 11m.
