Question

Jolon needs to fence a garden. The dimensions of the garden are meters by 4 meters. How much fencing does Jolon need to purchase?

Step-by-Step Solution

Answer

Jolon needs to purchase $20 \text{\hspace{0.17em}m}$ to fence the garden.

Step 1. Given information.

Dimensions of garden-

Length $=6\mathrm{m}$

Width $=4\mathrm{m}$

Step 2. Write the concept.

Fence required will be equal to perimeter of garden.

And the garden is a rectangular,

So,

The perimeter of a rectangle is given by:

$P=2\left(\text{Length}+\text{Width}\right)$

Step 3. Write the expression for Perimeter.

Length of rectangle $=6\mathrm{m}$

Width of rectangle $=4\mathrm{m}$

The perimeter of figure is given by:

$P=2\left(6+4\right)$

Step 4. Simplify the expression.

The expression $P=2\left(6+4\right)$ can be simplified as in below.

$\begin{array}{c}P=2\left(6+4\right)\\ =2\left(10\right)\\ =20\text{\hspace{0.17em}m}\end{array}$
