Answer 1

ok so u see the signs where it shows where some of the sides are the same length?

Answer 2

yes

Answer 3

Area is 600. Perimeter is around 108.

Answer 4

please show work :)

Answer 5

So, again, you cut the shape into a square and triangle.
The square: 20x20=400
Triangle: (20x20)/2=200
200+400=600

Answer 6

ok

Answer 7

For the perimeter, 20+20+20+20+20+x
I'm pretty sure x would be \[20^{2}+20^{2}=x ^{2}\]
400+400=800 and then \[\sqrt{800}= circa28 \]
28-20=8, because the hypotenuse of the triangle on top would be x(The shortest line)+20 (the line on the bottom)

Answer 8

so where did you get 108?

Answer 9

20+20+20+20+20+x
x=8
100+8=108

Answer 10

okay:)
