Answer 2

Step-by-step explanation:

Let lenght of rectangle be x

width of rectangle = 4/5 x

perimeter of rectangle = 2(l+b)

therefore 2(x + 4/5x)

= 2(9x/5)

= 18x/5

18x/5 is perimeter of rectangle

and perimeter of rectangle is 90m

so 18x/5 = 90

18x = 90*5

18x = 450m

x = 450/18

x = 25

x is lenght of rectangle

so lenght of rectangle is 25m

width = 4/5 lenght

= 4/5 of 25

= 4*5

so width is 20m
