Question

The perimeter of rectangular field is 200m and it's breadth is 40m find its length

Answer 1

Answer:

perimeter=2(l+b)

200=2(l+40)

200/2=l+40

100=l+40

l=100-40

l=60

Answer 2

Answer:

Perimeter of rectangle = 2 (I + b)

200=2(I +40)

I+40=200/2

I+40 = 100

I=100-40=60m

length 60m
