Question

Ramiro se dedica a circular terrenos se le presenta un trabajo se circular un terreno cuadrado con una superficie de 470 metro cuadrados y le piden que lo circulen con 4 hilos de alambre de puas sobre postes. ¿cuantos metros lineales con alambre de puas nesecita?

Answer 1

346.88 meters

Explanation:

Given that the area of the square-shaped terrain is 470 square meters.

Let a be the side of the terrain, so

Area of the square-shaped terrain,
`a^2=470` square meters.

Therefore, the length of one side,
`a=\sqrt {470}=21.68` meters.

The length of single thread wire required in circulating the square-shaped terrain = the perimeter of the square-shaped terrain

As the perimeter of a square having side a = 4a

So, the length of single thread wire required in circulating the square-shaped terrain= 4 x 21.68 =86.72 meters

Therefore, the length of 4 thread wire required in circulating the square-shaped terrain= 4 x 86.72=346.88 meters.
