Answer 1

number 3

Answer 2

do I need to cut the square in half

Answer 3

@angle

Answer 4

To find the perimeter you have to add up the length everything around it
For example,

you would have to add up all of the sides
which is 9 + 9 + 8 + 8 = 34
So the perimeter would be 34

for the area, I believe you can cut the square in half then find the area of both squares then add it together,

@az

Answer 6

i thought you had to Xs all the sides up >.<

Answer 7

hmmm

Answer 8

tbh IDK how to do any of it

not square, you have to make it two rectangles

Like this

Answer 10

We need a better screenshot since the numbers at the bottom got cut

but for perimeter- it's straightforward, just add the lengths of all the sides

for area, you find the area of each rectangle and add them together

Answer 12

there you go

so what is the length of this side that I'm marking in red?

Remember, the entire side is 12 on the left side but on the right side, we only have 9

so that means the red side is the difference between the two numbers

so it has to add with 9 to make 12

Answer 13

so 3

Answer 14

after that, you should be able to find the perimeter

you just add up all the sides

Answer 15

Yup!

So add up all the sides

we have a side with 12, 9, 12, 6, and 3

add them all up

Answer 16

42

Answer 17

that's your perimeter!

Answer 18

To find the area, we need to find the area of both rectangles and add them up

so let me separate the two rectangles

area = length * width

what are the areas of both rectangles?

Answer 19

so 9 times 6

Answer 20

no, each rectangle is separate

Answer 21

one of them is 6 by 3

the other is 9 by 12

Answer 22

don't get confused by the 12 in your question- that was the entire length but when you split it into two rectangles, you get one with a side of 3 and the other with a side of 9

Answer 23

what is the area of the rectangle on top?

you just have to multiply the two sides

Answer 24

18 and 108

Answer 25

for the first one 18 the second 108

Answer 26

good so the area for the entire figure is going to be the area of the two smaller shapes added together

so area = 18 + 108

area =

Answer 27

a=126

Answer 28

and that's your answer for the area :)
