Question

The area of a square ground is 42025 metre square.Find the perimeter of the field.​

Answer 1

`\boxed{820 \: m}`

Explanation:

Given,

Area of square ground = 42025

Now, let's find the length of square ground

Area of square =
`= {l}^(2)`

plug the values

`42025 = {l}^(2)`

Swipe the sides of the equation

`{l}^(2) = 42025`

Squaring on both sides

`\sqrt{ {l}^(2) } = √(42025)`

Calculate

`l = 205` meters

The length of square ground = 205 meters

Now,Let's find the perimeter of square

Perimeter of square
`= 4l`

plug the value of length

`= 4 * 205`

Multiply the numbers

`= 820` meters

Hope I helped.
