Question

What is the perimeter of rectangle ABCD if these are the points: A(0,0) B(0,5) C(10,5) D(10,0)

A. 20 units
B. 30 units
C. 40 units
D. 50 units

Answer 1

you can either realize that if you graph this its a simple rectangle or you can go the hard route and use the distance formula between AB and BC.

Answer 2

drawing a rough graph is much easeir

Answer 3

Okay I don't know how to graph and I don't know a what the distance formula. Do I just draw a rectangle and say that each corner are the points?

Answer 4

Yes.

Answer 5

the perimeter is the sum of the 4 lengths.

Answer 6

The perimeter is the distance around the rectangle.

Answer 7

you know how to plot the points, right? then count the number of units on each side (point to point)

Answer 8

I give up. This only confused me more than it helped

Answer 9

Pretend that the rectangle is a field.

Ask yourself how far do I walk if I want to walk all the way around the field.

Answer 10

Please don't give up :-)

Answer 11

Four parts:

1) from A(0,0) to B(0,5)
Distance from A to B is 5 units.

2) from B(0,5) to C(10,5)
Distance from B to C is 10 units.

3) C to D

4) D to A

Total distance traveled is
(1) + (2) + (3) + (4) = ?

You should get 30 units as your answer right? @BlueTigress120

Answer 12

I am so sorry if I confused you. Never give up. Please read it would really help and I won't respond again. Don't want to confuse you.
