Quiz 4
Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle:
A(2, -3), B(4, -3), C(4,5), and D(2,5).
What is the perimeter of rectangle ABCD?
units

32 units

Step-by-step explanation:

step 1

Plot the vertices to better understand the problem

we have

A(2, -3), B(4, -3), C(4,5), and D(2,5)

using a graphing tool

see the attached figure

The perimeter of the rectangle ABCD is equal to

where

----> difference of the x-coordinates

--> difference of the y-coordinates

substitute

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000
