Question 114

Solve the following 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

Let the number be x. Then, number of unit squares $=x\times x=x^2$
But total number of unit squares = 256
$\therefore x^2=256$
$\Rightarrow x=\sqrt{256}=\sqrt{16\times 16}=16$
Hence, the required number of squares is 16.
