Question

9. A man covers 84 m while going round a square field twice. Find the side of
the field.​

Answer 1

Answer:

Distance covered by a man = 84m

Perimeter of the square feild = distance covered by a man in one round = 84/2 = 42m

side of the square = 42/4 = 10.5m

Answer 2

Given:

Distance covered by man by going around the square field twice = 84m

To find:

Side of the field.

Let's do!:

Distance covered by the man if he goes once around the square field = $\frac {84}{2}$m

= 42m

Now, as we know that we need to find the side of the field, and the man is going around the field, therefore we will find the perimeter of the field. Here 42m is the perimeter of the square field.

Perimeter of square field = 4×side

42m = 4s

$\frac{42}{4} = s$

10.5 m = side

Final Answer:

Side of the square field is 10.5 m
