Answer 2

Given :

• Side of Square is 3.5 m .

To Find :

• Area and Perimeter of Square .

Solution :

For Area :

Using Formula :

$\longmapsto\tt\boxed{Area\:of\:Square=Side\times{Side}}$

Putting Values :

$\longmapsto\tt{3.5\times{3.5}}$

$\longmapsto\tt\bf{12.25\:{m}^{2}}$

So , The Area of Square is 12.25 m² ..

Now ,

For Perimeter :

Using Formula :

$\longmapsto\tt\boxed{Perimeter\:of\:Square=4\times{Side}}$

Putting Values :

$\longmapsto\tt{4\times{3.5}}$

$\longmapsto\tt\bf{14\:m}$

So , The Perimeter of Square is 14 m .

_______________________

• Diagonal of Square = √2 a (a = side of square )
• Perimeter of Square = 4 × Side
• Area of Sqaure = Side × Side
• Diagonal of Rectangle = √(l)²+(b)²
• Perimeter of Rectangle = 2(l+b)
• Area of Rectangle = length × breadth
