The area of a square playground is 256.6404 square metres. Find the length of one side of the playground.

Given:

Area of a square playground is 256.6404 square metres.

To do:

We have to find the length of one side of the playground.

Solution:

Area of the square playground $= 256.6404\ sq. m$

Therefore,

Side of the square $=\sqrt{\text { Area }}$

$=\sqrt{256.6404}$

$=\sqrt{\frac{2566404}{10000}}$

The square root of 2566404 is,

 1602 1 25664041 26 156156 3202 6404    6404 0
Therefore,

$\sqrt{\frac{2566404}{10000}}=\frac{1602}{100}$

$=16.02\ m$

The length of one side of the playground is 16.02 m.
