Question

Each side of a square field is$28m$. Find the:

(i) Perimeter of the square.

(ii) Cost of fencing the field at the rate of $20$ $RsperMeter$

Answer 1

Step1 Finding the perimeter of the square

(i) We have,

$$\begin{gathered} \text{Perimeter of square=4×Side} \\ \text{=4×28 cm} \\ \text{=112 cm} \end{gathered}$$

Therefore, the perimeter of the square is$112cm$

Step2 Finding the cost of fencing the field

(ii) Cost of fencing the field $=$ $112\times ₹20$

$=$ $₹2240$

Hence, the cost of fencing the field is $₹2240$
