Question

One side of a rectangular field is 65m. and the length of the side which is
perpendicular to this side is 42m, and the side parallel to it is 65m. Anish starts
jogging around the boundary of the field. How much distance will he cover jogging 6
laps around the field?​

Answer 1

Answer:

Given,

Side of the square field =65m

So, perimeter =4×side=4×65=260m

Now, the perimeter of a rectangular field =260m

And given length (l)=75m

∴  Perimeter of rectangle =2(l+b)

⇒260=2(75+b)

⇒260=150+2b

⇒2b=260−150

⇒b=

110

​  

=55 m

Then,

Area of square field =(side)  

2

=(65)  

2

=4225m

Area of rectangular field =l×b

=75×55 m=4125 m

Hence, it is clear that area of square field is greater.

Difference =4225−4125=100 m

Answer 2

Answer:

L =65m ,. B =42m. distance for 6 laps

=6*2(L+B) = 12*(65+42)=1284
