Find the cost of fencing a square field of side 18m with three rounds of barbed wire at the rate of 5 per metre​

Answer 1

$\huge{\underline{\underline{\rm{\purple{QuesTion:}}}}}$

Find the cost of fencing a square field of side 18m with three rounds of barbed wire at the rate of 5 per m.

$\huge{\underline{\underline{\rm{\purple{AnsWer:}}}}}$

Side of the square field = 18m

We have to find the perimeter of the square because it is to be fenced (Fencing is usually around an area...So, perimeter)

Perimeter of the square = 4 × Side

==> 4 × 18

==> 72m

Rate to fence a meter = Rs.5

Rate to fence 72 meters = Rs.5 × 72

==> Rs.360

The area is fenced with three rounds.

==> 3 × Total rate for fencing 72m

==> 3 × Rs.360

==> Rs.1080

$\huge{\underline{\underline{\rm{\purple{KnOw\:moRe:}}}}}$

Perimeter of a square = 4 × Side

Area of a square = Side × Side

Perimeter of a rectangle = 2 × (length + breadth)

Area of a rectangle = length × breadth
