Question

The area of a square is $8c{m}^2$. What is the nature of its perimeter?

• A. Irrational
• B. Rational
• C. Integer
• D. Can't say

Answer 1

The correct option is A

Irrational

Area of the square is $8c{m}^2$.
Therefore, the length of each side = $\sqrt{8}$
Perimeter of the square = 4$\sqrt{8}$ = $8\sqrt{2}$.
Hence, the perimeter is irrational.
