Question

the question is the cost of fencing a square field at the rate of rupees 25 per metre is is rupees 1800 determine the length of each side off the square field​

Answer 1

Answer:

• Side = 18 m

Step-by-step explanation:

Given :-

Rate = ₹25 per m

Total cost = ₹1800

To Find :-

Length of each side

Solution :-

If there is fencing in the question then we need to find perimeter

So,

Cost of fencing = Rate × Perimeter

1800 = 25 × P

1800/25 = P

72 = P

Now

Perimeter of square = 4 × side

72 = 4s

72/4 = s

18 = s

Hence

The side of square is 18 m

Answer 2

★ Given :-

• Rate of Rupees = 25 per metre .
• Total Cost = Rs. 1800 .

⠀⠀⠀⠀⠀⠀⠀

★ To Find :-

• Lenght of each side = ?

⠀⠀⠀⠀⠀⠀⠀

★ Solution :-

⠀⠀⠀⠀⠀⠀⠀

∓ Here, it is given that, Rate of Rupess is 25 per metre . Total Cost is Rs. 1800 . And, we have to find the Length of each side .

⠀⠀⠀⠀⠀⠀⠀

• Now, let's solve step by step -----

⠀⠀⠀⠀⠀⠀⠀

∓ In this case, Fencing in given, therefore we have to find Perimeter .

⠀⠀⠀⠀⠀⠀⠀

$\bull\:\sf\pmb{Cost \: of \: Fencing = Rate \times Perimeter} \\ \\ \dashrightarrow \: \sf{1800 = 25 \times Perimeter} \\ \\ \dashrightarrow \: \sf{ \frac{1800}{25} = Perimeter } \\ \\ \dashrightarrow \: \sf \pmb{72 =Perimeter }$

⠀⠀⠀⠀⠀⠀⠀

∓ Now, we will find Perimeter of Square .

⠀⠀⠀⠀⠀⠀⠀

$\bull\:\sf \pmb{Perimeter \: of \: Square = 4 \times side} \\ \\ \dashrightarrow \: \sf{72 = 4 \times side} \\ \\ \dashrightarrow \: \sf{side = \frac{72}{4} } \\ \\ \dashrightarrow \: \sf\pmb{side = 18 \: meter}$

⠀⠀⠀⠀⠀⠀⠀

★ Hence :-

• Lenght of each side = 18 meter .
