Take a look at the images given below. You might have come across objects like a photo frame, or a craft paper in day-to-day life. Can you identify what is common in them?

All of them have a square shape.

A square is a regular polygon having four equal sides and equal angles that measure 90° each.

A square is a two-dimensional closed shape with 4 equal sides and 4 vertices. Its opposite sides are parallel to each other. We can also think of a square as a rectangle with equal length and breadth.

Looking around, you can find many things that resemble the square shape. Common examples of this shape include a chessboard, craft papers, bread slice, photo frame, pizza box, a wall clock, etc.

Area represents space occupied by a shape or figure whereas perimeter is the length of the outer boundary of the shape. Let’s discuss the formula for finding the area and perimeter of a square.

The area of a two-dimensional shape is defined as the amount of space covered by the shape if we were to keep it on a flat table.

For a square of side length “s” units, the area is given by the formula:

Area $= \text{side} \times \text{side} = \text{S}^2$

The area is expressed in square units, such as $\text{cm}^2$, $\text{cm}^2$, etc.

The perimeter of a two-dimensional shape is defined as the total length of its boundary.

For a square of side length “s” units, the perimeter is given by the formula:

Perimeter $= \text{side} + \text{side} + \text{side} + \text{side} = 4$ $\text{x}$ $\text{s}$

The perimeter is expressed in linear units, such as cm, inches, m, etc.

Example 1: The side of a square paper is 12 feet. Find the area of the paper.

Solution:

We know that the area of a square is given by $\text{s}^2$, where $\text{s} =$ length of the side.

For the given square, s $= 12$ feet

Therefore, the area of the square paper is given by:

Area $= \text{s}^2 = 12 \times 12 = 144$ sq. ft.

Example 2: If the perimeter of a square measures 68 cm, what is the measure of its side?

Solution:

We know that the perimeter of a square is given by 4 x side.

It is given that the perimeter is 68 cm.

Therefore, 4 x side $= 68$

Which means, side $= \frac{68}{4} = 17$ cm

Example 3: What is the perimeter of a square that has a side of 15 meters?

Solution: We know that the perimeter of a square is given by 4 x s, where s represents the length of each side.

It is given that the side s $= 15$ meters.

Therefore, perimeter $= 4 \times 15 = 60$ meters.

• Make a left at the wall and follow it all the way down until you reach a small doorway that takes you right.
• Make that right and you will see a metal box.
• Make a right at the box and continue straight.
• Make your next right.
• From here on, there are no openings and the path does not split off.

I received some bmz named jeans, which was pathetic. I ordered nifty jeans.
