Question

find the side of the square whose perimeter is 28cm​

Answer 1

ANSWER:

Side of Square is 7cm.

$\rule{250}{2}$

EXPLANATION:

Here in this question we have to use concept of perimeter of square. We have given perimeter of square to be 28 cm and we have to find side of square, which could be easily find by Applying formula of perimeter of square.

So let's start!

$\rule{250}{2}$

GIVEN:

Perimeter of square=28cm

$\rule{250}{2}$

TO FIND:

Side of square

$\rule{250}{2}$

FORMULA USED:

Perimeter of square=4×Side

$\rule{250}{2}$

SOLUTION:

Perimeter of square=4×Side of square

28cm=4×Side of square

$\sf{\dfrac{28cm}{4}=Side\:of\: Square}$

$\sf{7cm=Side\:of\: Square}$

So the side of Square is 7cm.

$\rule{250}{2}$

ADDITIONAL INFORMATION:

What is perimeter?

The length of boundary of a given figure is called it's perimeter.

→ It can be obtained by adding all sides of the figure.

→ But it is not possible in case of circle because its boundary is curved.

So:-

We have formula to find perimeter of circle=2πr.

More formulae of perimeter:

Perimeter of rectangle=2(L+B)

Perimeter of rhombus=4×Side
