Question

the cost of putting fence around a square field at rs 15 per m is rs 432 find the length of each side of the field​

Answer 1

Answer:

The measure of each side is 7.2 cm.

Step-by-step explanation:

Given :

Cost of putting the fence = Rs. 432

Rate of fencing = Rs. 15 per m

To find :

The measure of the Square field's each side

Solution :

★ $\textsf{\underline{\underline{Divide the cost - }}}$

Divide the cost of fencing with the rate of fencing to get the perimeter of the Square.

$\sf{\implies} \: \dfrac{432}{15} \\ \\ \sf{\implies} \: 28.8$

Perimeter = 28.8 m

$\rule{300}{1.5}$

★ $\textsf{\underline{\underline{Measure of its side - }}}$

Let the side be y

$\sf{Perimeter = Side \times 4}$

$\sf{\implies} \: 28.8 = y \times 4 \\ \\ \sf{\implies} \: y = \dfrac{28.8}{4} \\ \\ \sf{\implies} \: y = 7.2$

Side = 7.2 cm

$\therefore$ The measure of each side is 7.2 cm.

Answer 2

Answer:

The measure of each side is 7.2 cm.

Step-by-step explanation:

Given:

Cost of putting fence = Rs. 432

Rate of fencing = Rs. 15 per m

To Find Out:

The measure of the square field of each side.

Solution:

On dividing the cost of the fencing with the rate of fencing to get the perimeter off the square.

=> 432 / 15 = 28.8 m

.°. Perimeter = 28.8 m

Now, find the measure of its side.

Let the side be y

As we know that,

[ Perimeter of Square = 4 × Side ]

=> 28.8 = y × 4

=> 28.8 = 4y

=> y = 28.8 / 4 = 7.2

.°. y = 7.2 m

So, the measure of each side is 7.2 m.
