Question

the area of square is 1444m² find the cost of the fencing of the field at the rate rs 5 per m​

Answer 1

Area = 1444m^2

Side = root 1444 = 38m.

Fencing = perimeter = 4 × side

4×38 = 152 m

Cost of fencing = 152×5 = 760Rs.

Answer 2

Step-by-step explanation:

given area of a square = 1444m^2.

we know area of a square = a^2

so, a^2(side into side) = 1444.

a (side) = ±√1,444.

a= ±38.

side cannot be negative so side of the given square is 38.

we know the perimeter of a square = 4a.

so,4a = 4(38)

=》152 m

given cost per meter of fencing is 5rs .

so the total cost of fencing is 152 × 5

= 760 rs.

therefore the cost of the fencing of the field at the rate rs 5 per m is 760 rs
