Example Question #1 : How To Find The Perimeter Of A Quadrilateral
A homeowner wants to set up a rectangular enclosure for his dog. The plot of land that the enclosure will enclose measures by . What is the length in feet of chain link fence the owner will need to create a fence around the enclosure?
To answer this question, we must find the perimeter of the fence the homeowner is wanting to create.
To find the perimeter of a rectangle, we multiply the length by two, multiply the width by two, and add these two numbers together. The equation can be represented as this:
We must then plug in our values of and given to us for the length and width.
So for this data:
Therefore, the amount of fencing needed to fully surround the dog's enclosure is .
