Question

The cost of putting a fence around a square field are at 35 per metre is 4480 find the length of each side of the field

Answer 1

Answer:

32 m

Step-by-step explanation:

Let the side of square field be 'x' m

Since, it's said that the field is fenced.

Therefore, we need to find the Perimeter.

Therefore, we will get,

=> Perimeter = 4x m

Now, Cost of fencing 1 m = ₹ 35

Therefore, cost of fencing 4x m = ₹(35×4x)

But, it's given that,

The cost is equal to ₹ 4480

Therefore, we will get,

$= > 4x \times 35 = 4480 \\ \\ = > x = \frac{4480}{4 \times 35} \\ \\ = > x = \frac{1120}{35} \\ \\ = > x = 32$

Hence, the length of each side is 32 m.

Answer 2

Answer:

cost of fencing 35/meter=4480,

number of metres =4480/35=128

number of sides of square =4,

circumference of square=128

so,length of square=128/4=32 metres
