MCQ
Mark the correct alternative in the following question: The perimeter of a square whose area is $225\ m^2$ is:
 
  • A
    $15\ m$
  • ✓
    $60\ m$
  • C
    $225\ m$
  • D
    $30\ m$
✓

Answer

Correct option: B.
$60\ m$
We have,
Area of the square = $225\ m^2$
As, the side of the square $=\sqrt{\text{Area}}$
$=\sqrt{225}$
$=15\text{m}$
So, the perimeter of the square $= 4 \times side$
$=4 \times 15$
$=60\ m$
