All I can help with is that the very bottom left angle is 60 degrees
Let L be the length
Let w be the width
Let p be the perimeter
L+w+L+w=p
L=w+20
3L+2w+3L+2w=240
Sub the first equation in for L in the second equation and solve for w
3(w+20)+2w+3(w+20)+2w=240
3w+60+2w+3w+60+2w=240
10w+120=240
10w=240-120
10w=120
W=120/10
W=12
Sub w into the first equation and solve for L
L=w+20
L=12+20
L=32
Hope this helps!
10+16=26 so there for your answer would be 26 if you need it more described let me know
Forget about the minus sign until you're done, then slap it back on.
-1 1/2 = -(1 1/2) = -(3/2) = -3/2
