Question

What will be the number of unit squares on each side of a square graph paper if the total number of unit squares is 256?

Answer 1

From the question it is given that,

The total number of unit squares is = 256.

Let us assume the number be ‘a’

We know that, a × a = a²

So,

a × a = 256

a² = 256

a = √256

a = √(16 × 16)

a = √16²

a = 16

∴The number of unit squares are 16.
