Question

3
The perimeter of a trapezium is 55 cm and its non-parallel sides are
8 cm and 7 cm. The difference between the lengths of the parallel
sides is 5 cm. Find the lengths of the parallel sides.​

Answer 1

Step-by-step explanation:

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
