Question

A rectangle on a coordinate plane has vertices at (7,5), (-7, 5), (-7, -2), and (7, -2). What is the perimeter of the rectangle?

Answer 1

Answer : The perimeter of rectangle is 42

Answer 2

Answer:

The perimeter of the rectangle is 36 units (or whatever you're using to measure the length and width of the rectangle).

Step-by-step explanation:

First: You need to find the change in x of all the values. The different values of x in the coordinates given are: 7 and -7. The difference between these two is 14. This will be the rectangle's length.

Second: You need to find the change in y of all the values. The different values of y in the coordinates given are: 2 and -2. The difference between these two is 4. This will be the rectangle's width.

Third: Now that you know the length and the width of the rectangle you use the formula for perimeter to find its perimeter, which is:

Perimeter = 2( length + width )

Now we just plug in the values:

Perimeter = 2( 14 + 4 ) = Perimeter = 2( 18 ) = Perimeter = 36

So the perimeter of the rectangle is 36 units
