Question:
The area of rectangular lawn is 225 sq. M .if its length is 15 meter fund its perimeter
Answer:

Let breadth of the rectangular lawn is b

Given length of the rectangular lawn is 15 m

Now area of the rectangular lawn = 225

=> length*breadth = 225

=> 15*b = 225

=> b = 225/15

=> b = 15

Perimeter of the rectangular lawn = 2(length + breadth)

                                               = 2*(15 + 15)

                                               = 2*30

                                               = 60 m
