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

Answer 1

Area of square playground = 256.6404 sq.m
$\therefore$ Side of the square $=\sqrt{Area}$
$=\sqrt{256.6404}=\sqrt{\frac{2566404}{10000}}$

$=\frac{\sqrt{2566404}}{\sqrt{10000}}=\frac{1602}{100}=16.02m$
