Question

The perimeter of a trapezium is 55cm and its non-parallel sides are 8cm and 7cm.The difference between the length of the parallel sides is 5cm.find the length of the parallel sides.

please answer it fast. ​

Answer 1

draw ur trapezium & let d shorter parallel side =y &d longer=x

perimeter of trapezium=7+8+x+y=55

and x -y=5

==>x=5+y

substituting

15+5+y+y=55

20+2y=55

2y=55-20

=35

y=17.5

x=22.5
