Question

The perimeter of a square is 140m. Find its area:​

Answer 1

Step-by-step explanation:

the area if square is :(side)2

when we multiply 140×140

your answer is=19,600

Answer 2

$\Large{\underbrace{\sf{\purple{Required\:Solution:}}}}$

Given :

• The perimeter of α squαre is 140m.

To Find :

• Areα of the squαre.

Procedure :

Firstly we'll αssume the side of squαre to be x then find the αctuαl vαlue of side by using the formulαe of perimeter αnd put vαlue of side in the formulαe of αreα of the squαre αnd we'll done! :)

So, let's do it!

Step by step explαnαtion :

Let's the side of the squαre be x.

According to the question,

:$\implies{\sf{ 4x = 140m}}$

:$\implies{\sf{ x = \dfrac{140m}{4}}}$

:$\implies{\sf{ x = 35m}}$

Now,

we know thαt,

$\large\star{\boxed{\sf{\purple{ Area_{(square)} = (side)^{2}}}}}$

• Substitute the vαlues αnd simplify.

$\longrightarrow{\sf{ (35cm)^{2} }}$

$\longrightarrow{\sf{ 35cm\times 35cm}}$

$\large\implies{\boxed{\sf{\purple{ 1,225cm^{2}}}}}$

Hence, the αreα of the squαre is 1,225cm².

And we αre done! :D
