Question

a rectangular piece of land measures 7 m by 5 m. each side is to be fenced with 4

Answer 1

Answer:

The perimeter of a rectangular piece of land = 2(Length + Breadth)

The perimeter of a rectangular piece of land = 2(Length + Breadth)

The perimeter of a rectangular piece of land = 2(Length + Breadth) = 2(0.7+0.5)

The perimeter of a rectangular piece of land = 2(Length + Breadth) = 2(0.7+0.5)= 2(1.2)

The perimeter of a rectangular piece of land = 2(Length + Breadth) = 2(0.7+0.5)= 2(1.2)= 2.4 km

∵1km = 1000m

∴0.24 = 1000×0.24=2400 m.

Since 4 rows of wire is required.

∴2400×4=9600 m

∴9600 m = 9.6 km

Therefore, length of wire required is 9.6 km or 9600 m.
