Answer 1

I hope it will help you

Answer 2

hiii!!!

here's ur answer...

given the Length of the rectangular playground is 90m

area of the rectangular playground = 3600m²

therefore l×b = 3600m²

=> 90×b = 3600m²

=> b = 3600/90

=> b = 40m

verification:-

area of the rectangular playground = l×b

= 90×40

= 3600m²

hence verified

thus the breadth of the rectangular field is 40m

now,

perimeter of the rectangular playground = 2(l+b)

= 2(90+40)

= 2×130

= 260m

hope this helps..!
