Question

Q5. A rectangular piece of land measures 0.7 km

Answer 1

Answer:

$Amount = 9.6km$

Explanation:

Given

$Length = 0.7km$

$Width = 0.5km$

$Wires = 4$

Required

Determine the length of wire needed

First, we calculate the perimeter of the land.

$Perimeter = 2*(Length + Width)$

$Perimeter = 2*(0.7km + 0.5km)$

$Perimeter = 2*(1.2km)$

$Perimeter = 2.4km$

That is the amount needed for 1 row of wire.

For 4 rows, it would be:

$Amount = 4 * Perimeter$

$Amount = 4 * 2.4km$

$Amount = 9.6km$
