Answer 2

the length and bredth are 25 and 20 respectively.

the sides of the rectangle are in ratio 5:4.

let the ratio be x.

so, length be 5x.

breadth be 4x.

perimeter of rectangle=2(l+b)

                                     =2(5x+4x)

                                     =2*9x

now perimeter given 90cm

2*9x=90

18x=90

x=90/18

x=5

so length=5x=5*5=25

and breadth=4x=4*5=20

area=l*b

=25*20

=500   ANS.....

hence the length is 25 and breadth is 20.
