Question

The perimeter of a square board is $\frac{4}{5}m$ . What is the length of its each side?

Answer 1

Let the length of each sides of the square board be $a$ cm.

Then according to the problem,

$4a=\frac{4}{5}$

or, $a=\frac{1}{5}$.

So length of each sides of the square board be $\frac{1}{5}$ cm.
