Question

Find the area of square whose perimeter is 48m.

Answer 1

SOLUTION :

The perimeter of a square = 48 m     (given)

To be found :

The area of the square

We know that,

The perimeter of square = 4a unit   [ ∴ In which a is the side of the square ]

First we have to find the side of the square

We can find the side of the square by the perimeter of the square

⇒ 4a = 48  

⇒ a = $\frac{48}{4}$

⇒ a = 12

∴ The side of the square is 12 m

Now,

Area of the square = $\bf{ {a}^{2} }$  unit sq.    [ ∴ In which a is the side of the square ]

Area of the square =  $\bf{ {(12)}^{2} }$ m sq.  

Area of the square = 144 m sq.

Hence,

The area of the square is 144 m sq.
