Question

If the perimeter of a square is 280 m, then the area of the square is ______.

• A. 4500 $m^2$
• B. 4900 $m^2$
• C. 280 $m^2$
• D. 1400 $m^2$

Answer 1

The correct option is B 4900 $m^2$

Given,
Perimeter of a square = 280 m

Perimeter of a square = 4 x Side

$\Rightarrow$ 4 x Side = 280 m
$\Rightarrow$ Side = $\frac{280m}{4}$
$\Rightarrow$ Side = 70 m

$\therefore$ Area of the square = $Sid{e}^2$
= ${\left(70m\right)}^2$
= 4900 $m^2$
