Answer 1

So what part are you stuck on?

Answer 2

the second link number 8-13

i know alot of questions

Answer 3

Okay, so what are you stuck on and what steps have you tried towards solving?

Answer 4

so far 9,10,and 11

Answer 5

Alright, looking at 9. What part of the overall shape does each rectangle share?

Answer 6

This link had all the diagrams needed to anser the questions

Answer 7

I looked at both pictures, I have answered all of the questions. I am trying to help you answer them as well.

Answer 8

ohhhh please be more specific.........i think each rectangle share the triangles right

Answer 9

I think you do 70 ft and 20 ft for number 9 because 120 - 80 = 40ft and since there are two rectangles divide it by two to get 20 ft... something like this

Answer 10

Question 9 asks you how you might figure out the length and width of the smaller rectangles, part C of your "Picture it" section.
Looking at just the two C shapes, how might you get the length and width?

Answer 11

so am i right...... you do 70 ft and 20 ft for number 9 because 120 - 80 = 40ft and since there are two rectangles divide it by two to get 20 ft... something like this

Answer 12

Yes, exactly. Excellent work.

Answer 13

How about 10?

Answer 14

add up all the areas of each simpler figure

Answer 15

Yes, again you have nailed it.

Answer 16

How about 11?

Answer 17

Since there are four triangles, add 100 sq ft four times and add 1,400 sq ft two times since there are two small rectangles, then add b which is 7,200 sq ft I think

Answer 18

Are you doing the second part of 10?

Answer 19

oops sorry kinda got mixed up

Answer 20

Alright, which one would you like to work on?

Answer 21

11.......I think the total area is 10,400 sq ft, and since it is $2.50 per sq ft, multiply it

Answer 22

And what was your final answer?

Answer 23

$26000 i think

Answer 24

100% correct, guess you didn't need help at all. :)

Answer 25

heh hold on their is still 12 and 13 :) :P

Answer 26

I was also a bit confused at first, but then I figured it out before we went through the steps

Answer 27

^oh hey justin

Answer 28

Well then let's look at 12, how would you take this one on?

Answer 29

hmmm well i kinda have troubles on this one

Answer 30

Okay, so it gives you a hint about using subtraction. Looking at the picture, what measurements do you know that would allow you to subtract to get the shaded area?

Answer 31

7,200 sq ft and 100 sq ft?.........well it says outer rectangle and corner triangles

Answer 32

Well forget about the first part of your answer and look at the last part. You see that there are unshaded triangles in the corners of the total area. You could calculate the total and "subtract" those triangles to get the shaded portion.

Answer 33

ohhh

Answer 34

so like multiply 90 by 120 then subtract the unshaded region

Answer 35

Indeed. Excellent work.

Answer 36

Yes that does work.

Answer 37

It still is 10,400 square feet.

Answer 38

so its correct

Answer 39

now 13

Answer 40

Actually, it is exactly 10400.

Answer 41

Which just shows you that both ways will work since you get the same answer. Okay, 13 wants you to find the area of this polygon. Using techniques that you employed on the larger shape, how could you approach this problem?

Answer 42

May I try to see if I am correct?

Answer 43

If that is alright with @alvinawesome

Answer 44

She messaged me saying yes, and it appears she also left

Answer 45

Okay, how would you approach this?

Answer 46

I think there are two triangles shown with the dotted lines, and the length of it is 7cm of the triangle, but I am not sure. And each triangle is 4cm since it says 8cm as the height and both triangles are half of 8

Answer 47

The shape doesn't look accurate to show 7cm

Answer 48

Okay, you are right and on a good path. So you're saying we have this:

Answer 49

The thing that you are forgetting is that we have two sides.

Answer 50

So we really have this:
