Chapter 11: Q4. (page 425)

The perimeter of a square is $28 c m$ .What is the area?

Short Answer

Expert verified

The area of the square is $49 c m^{2}$

Step by step solution

Step 1. Given information.

Perimeter of the square is $P = 28 c m$ .

Step 2. Concept Used.

If is the side of the square

Then, the area of the square is $A = {(s i d e)}^{2}$

Perimeter of the square:

$P = 4 \times (s i d e)$

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

Put the value of perimeter into the formula and find the side length.

Perimeter of the square:

$\begin{matrix} 28 = 4 \times (s) \\ s = \frac{28}{4} \\ s = 7 c m \end{matrix}$

Area of the square:

$\begin{matrix} A Invalid <m:msup> element = \\ = 49 c m^{2} \end{matrix}$

Therefore, the area of the square is $49 c m^{2}$
