A bakery is 15 yards wide and 24 yards long. The baker wants to put a wooden shelf aroundthe inside of the bakery. The wooden shelving costs $6.00 per yard. How much will thebaker's shelf cost?

Sagot :

First, we need to calculate the perimeter of the bakery.

The perimeter is given by the sum of all sides:

[tex]\begin{gathered} P=2\cdot length+2\cdot width\\ \\ P=2\cdot24+2\cdot15\\ \\ P=48+30\\ \\ P=78\text{ yd} \end{gathered}[/tex]

If the cost per yard of the shelf is $6, the total cost will be:

[tex]\begin{gathered} Cost=6\cdot perimeter\\ \\ Cost=6\cdot78\\ \\ Cost=468 \end{gathered}[/tex]

Therefore the shelf will cost $468.
