Question

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

• A. 1 units
• B. 2 units
• C. 4 units
• D. 8 units

Answer 1

The correct option is C 4 units

Let the side of the square be a units.

Perimeter of the square, P = 4a units
Area of the square, A = a${}^2$ units${}^2$

Given:
Area = Perimeter
$\Rightarrow$ a${}^2$ = 4a
$\Rightarrow$ a = 4 units

$\therefore$ Measure of side of the square = 4 units
