Question

The area of trapezium is 225cm.sq units and its height is 15cm .if one of parallel side is longer by other than 6.

Answer 1

Step-by-step explanation:

let one parallel side=x

other=x+6

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

225= 1/2× x+x+6×15

225=1/2+6+2x×15

225×2/15=6+2x

30=6+2x

24=2x

12=x

thus one parallel side=12

other =12+6=18.....
