Answer 2

30 metres

Step-by-step explanation:

Let the length of rectangular field be x

Breadth of rectangular field = 15 m

Perimeter of rectangular field =2(l+b)=2(x+15)

We are given that perimeter is 90 meter

So,2(x+15)=90

x+15=45

x=30

Hence, the length of the rectangular field is 30 metres.
