Q3. - Geometry

Question

Find the area and perimeter of a square with sides $5cm$long.

Step-by-Step Solution

Answer

The area of the square is$25c{m}^2$ and perimeter is$20cm$ .

Step 1. Given information.

Each side of the square is$5cm$ long. 

Step 2. Concept Used.

If is the side of the square

Then, the   area of the square is $A={\left(side\right)}^2$

Perimeter of the square:

$P=4\times \left(side\right)$

Step 3. Let’s calculate the area and perimeter of the square.

Put the value of side into the formula.

Area of the square:

$\begin{array}{c}A=\left(5cm\right)\\ =25c{m}^2\end{array}$

Perimeter of the square:

$\begin{array}{c}P=4\times \left(5cm\right)\\ =20cm\end{array}$

Therefore, the area of the square is$25c{m}^2$ and perimeter of the square is$20cm$ .
