Question

The side length of a square can be expressed by the formula s=√A where A is the area of thw square. I f the area of the square is 50m², what is the length of its side?

Answer 1

Since the area of th e square is 50m², then

A= 50m².

From the formula $s=\sqrt A$ ,

The side length $s=\sqrt 50$ m

$s=\sqrt (5 \times 5\times 2)$ m

so, $s=5\sqrt 2$ m.

or $s\approx 7.0710678$ m
