Answer 2

Question:

If a perimeter of a square sheet is 420 m, find the side of square and the area.

Now,

Let the side of square be '$x$' m.

Given,

The area of perimeter of square sheet is 420 m.

Thus,

$4x=420$

$x=420\div4$

$x=105$

Hence,

The side of square sheet with perimeter of 420 m is 105 m.

So,

Area = $Side$ × $Side$

= $105$ × $105$

= $11,025$

Therefore,

The area of the square sheet is $11,025$ $m^2$
