karatechopper · Answer

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

anonymous · Answer

yes

anonymous · Answer

Area is 600. Perimeter is around 108.

anonymous · Answer

please show work :)

anonymous · Answer

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

anonymous · Answer

ok

anonymous · Answer

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)

anonymous · Answer

so where did you get 108?

anonymous · Answer

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

anonymous · Answer

okay:)
