How To Find The Perimeter Of A Square Or Rectangle

Perimeter of a Square

A foursquare is a type of rectangle in which the side by side sides are equal. In other words, all the sides of a foursquare are equal.

Following are the properties of a square:

(i) All the angles in a square are the same and equal 90º.

(ii) All the sides of a square are equal.

Perimeter of a square

The perimeter of a square is the total length of all the sides of the square. Hence we can detect the perimeter of a foursquare past adding all its four sides.

The perimeter of the given square is a + a + a + a. Since all sides of a square are equal, we only need 1 side to find its perimeter.

The perimeter of the given square is:

a + a + a + a = iv  a units.

Hence, the formula of the perimeter of a square = four × (length of any 1 side).

Tricky math problems with the squares:

Type I: Finding side length when only the perimeter is given.

Example 1. If the perimeter of the given square is 12 cm. What will be the length of its side?

Solution: Given, the perimeter of the foursquare is 12 cm.

Let the side length be 'a' cm.

Nosotros know that, the perimeter of a square = iv × (side length)

12=iv×(a)

a = 3 cm

Type Ii: Finding sides using square properties.

Instance 2.If a = 4 cm in the given square. Discover b, c. and d.

Solution: Given that side a = iv cm.

To discover side b, c, and d  we apply the holding of the square which states that all the sides of a square are equal.

Therefore, a = b = c = d = 4 cm

Blazon III: Finding perimeter when i of the sides is given.

Example 3. One of the sides of a square is 5 cm. What volition be its perimeter?

Solution: Given, one side of the square is 5 cm.

We know that, the perimeter of a square = iv × (side length)

= 4×(five)

= xx cm

Example four. The length of a side of the foursquare wooden frame is 5 cm. Discover the total length of the wood used in the frame.

Solution: Given, the length of a side of this wooden frame is five cm.

Equally we know, the perimeter of a square = 4× (side length)

= 4  (5)

= 20 cm

Hence, the total length of the wood used is 20 cm.

  Fun Facts

• Squares are i of the iii most basic shapes on the earth. The other ii are circles and triangles.
