Question

the area of a trapezium is 120sqm if its height is 12m then the sum of its parallel side is​

Answer 1

Answer:

Here is your answer mate...

Given.:- Area = 120m^2

Height / Altitude = 12m

One parallel side = 10 m

Let the other parallel side be x ,

》 Area of trapezium = Height× (sum of parallel side) ÷2

》 120m^2 = 12m×( 10m + x ) ÷ 2

》 120m^2 = 60m + 6x

》 6x = 60m - 120m

》 6x = 60m

》 x = 60/6

》 x = 10m Ans.

So, the other parallel side is 10 m.
