Respuesta :

In order to calculate the amount of material needed to fence the garden, we can calculate the perimeter of the garden.

The perimeter is the addition of all sides that conform a figure, then,

[tex]\begin{gathered} P=6.2m+4.2m+2.8m+3m+3.4m+7.2m \\ P=26.8m \end{gathered}[/tex]

However, since the side against the house does not need fencing,

[tex]\begin{gathered} fence=P-7.2m \\ fence=26.8m-7.2m \\ fence=19.6m \end{gathered}[/tex]

Answer:

there are 19.6m needed in order to fence the garden.
