On a coordinate plane, the vertices of a rectangle are (2,4), (2,-1), (-5,-1) and (-5,4). what is the perimeter of the rectangle?

Step-by-step explanation:

we know that

The perimeter of the rectangle is equal to

where

L is the length side

W is the width side

In this problem we have

using a graphing tool

Plot the points

see the attached figure to better understand the problem

the formula to calculate the distance between two points is equal to

Find the distance BC

substitute

Find the distance AB

substitute

Find the perimeter

we have

substitute

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
