Question

1. Case study based- 1:
Mohan is a farmer. He has two plots of land having the same perimeter. One is square of side 60 m while the
other is a rectangle whose breadth is 15 m. In the rectangular plot Mohan builds a room and covers the floor
of the room by square tiles of side 3m.

i. What is the length of the rectangular plot?
​

Answer 1

Answer:

Thus length of the rectangular plot=105 m

Step-by-step explanation:

Let length of the rectangular plot=x m

Then its perimeter=2(x+15)=2x+30 m

Now perimeter of the square plot

=4*60=240 m

Given that

2x+30=240

2x=240-30=210

x=210/2=105 m

Thus length of the rectangular plot=105 m
