Question

When the perimeter and area of a square are numerically equal, what is the numerical value of the measure of its side?

• A. 1
• B. 2
• C. 4
• D. 8

Answer 1

The correct option is C

4

Let the side of the square be $aunits$
Perimeter of the square, $P=4aunits$
Area of the square, $A=a^{2}unit{s}^2$

Given that, A = P
$a^2=4a$
$\Rightarrow a=4units$
