Question

The perimeter of a square card board is 1m. Find its area in cm²

Answer 1

Answer:

Perimeter of Square = 1m

Perimeter of Square = 100cm

But, Perimeter of Square = 4×Side

So, 4×Side = 100cm

Side = (100/4) cm

Side = 25 cm.

Now, Area of Square = Side×Side

Area of Square = 25cm×25cm.

$625 {cm}^{2}$
