Question

20 a) The area of a square field is 84642. A man takes 3 rounds of this field. Find the distance covered by him.

Answer 1

So, the distance covered by man if he takes 3 rounds is 3491.16 inches

Explanation:

We are given area of square field i.e 84642 and we need to find distance covered by man if he takes 3 rounds of the field.

Distance covered by man = Perimeter of square field

First we have to find length of side of square field.

The formula used is Area of square= (Length)^2

Putting value of area and finding length.

`Area of square= (Length)^2\\√(Length) =√(84642) \\Length= 290.93\\`

So, length of square field is 290.93 inches

Now finding the distance covered by man if he takes 3 rounds

First find perimeter

Perimeter of square = 4*length

Perimeter of square = 4*290.93

Perimeter of square = 1163.72 inches

Distance covered by man if he takes 3 rounds = 3*Perimeter of square

Distance covered by man if he takes 3 rounds = 3*1163.72

So, the distance covered by man if he takes 3 rounds is 3491.16 inches
