Question

The length of the side of a square is x. Express its perimeter and area in terms of x.​

Answer 1

In context to questions asked,

We have to express the value of perimeter and area in term of X, where X is the value of side of square.

As we know that,

Area of square is equal to,

$area = {side}^{2}$

So, for determining the value of area we will put the value of side in above formula.

Thus we will get,

$area = {x}^{2} \: {unit }^{2}$

As we know that,

$perimeter = 4 \times sides = 4 \times x = 4x \: unit$

Answer 2

To express : perimeter and area of square in terms of $x$ .

Given : length of side of square $= x$

Solution :

• We know that all four sides of square are equal .

• If ' $x$ ' is the side of square then perimeter of square is given by,

• Perimeter of square $=4 x$
• Similarly , to find area we multiply length of side of square two times that is we find square of length of side .  
• Area of square = $x^{2}$  

Hence, perimeter and area of square are expressed as $4x$ and $x^{2}$ in terms of $x$ .respectively.
