Question

The area of square-shaped field is 484 sq.cm . Find the cost of fencing this field at the rate of Rs 12 per metre

Answer 1

Answer:

1056 rs

Step-by-step explanation:

The formula of area of a square is a² (a is length of a side of the square)

so,

${a}^{2} = 484$

$a = \sqrt{484} = 22$

the formula of range of the square is = 4 x a cm

$= 4 \times 22 \: cm$

$= 88 \: cm$

the cost of per meter for fencing is 12 rs

so the total cost is

$= 88 \times 12 \: rs$

$= 1056 \: rs$
