Question

The area of trapazium 279cm2 the distance between its parellel sides is 18cm and one of the perellel side is 13cm find the length of other side

Answer 1

Let the other parallel side is x

Area of trapezium =(sum of parallel sides) *height /2


Here, 279=(13+x)*18/2

279=(13+x) *9

279/9 =13+x

31=13+x

31-13=x

18=x



Then the other parallel side is 18cm
