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

answer: 1 2 3 6

step-by-step explanation:

1x6=6 2x3=6

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
