Q5) A rectangular piece of land measures 0.7 km by 0.5 km. Each side is to be fenced with 4 rows of wires. What is the length of the wire needed?

Solution

Transcript

Solution:

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

= 2(0.7+0.5)

= 2(1.2)

= 2.4 km

\because1km\ =\ 1000m∵1km = 1000m

\therefore0.24\ =\ 1000\times0.24=2400∴0.24 = 1000×0.24=2400 m.

Since 4 rows of wire is required.

\therefore2400\times4=9600∴2400×4=9600 m.

\therefore9600\ m\ =\ 9.6\ km∴9600 m = 9.6 km

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