Question

4. A rectangular field is 50 m 40 m. Nitin takes ten rounds of its boundary. How much distance does he cover?​

Answer 1

Perimeter of field=2(l+b)

=2(40+50)=2*90=180m

Hence for one round =180m

For 10 rounds=10*180=1800m

Answer 2

Length- 50m

Breadth -40m

Perimeter of a rectangle- 2(L+B)

2(50+40)

2× 90

180m

Since Nitin takes ten rounds so the distance covered by him will be - 10× 180 =1800m
