Question

find the cost of fencing a square field of side 35 m at the rate of ₹40 per meter ​

Answer 1

Step-by-step explanation:

perimeter =4×35

=140

cost of fencing =40×140

=Rs5600

Answer 2

Given :-

Side of the square field = 35 m

Rate of fencing per square meter = Rs. 40

To Find :-

The cost of fencing a square field.

Analysis :-

Firstly, find the perimeter of the field by substituting the values in it's respective formula.

Multiply the rate per meter to the perimeter in order to find the cost of fencing.

Solution :-

We know that,

• s = Side
• p = Perimeter

By the formula,

$\underline{\boxed{\sf Perimeter \ of \ square=4 \times Side}}$

Given that,

Side (s) = 35 m

Substituting their values,

Perimeter = 4 × 35

Perimeter = 140 m²

Therefore, the perimeter of the field is 140 m².

Cost of fencing = Perimeter × Cost per meter

Cost of fencing = 140 × 40

Cost of fencing = Rs. 5600

Therefore, the cost of fencing is Rs. 5600.
