P = 2(L + W)
P = 56
W = L - 6
56 = 2(L + L - 6)
56 = 2(2L - 6)
56 = 4L - 12
56 + 12 = 4L
68 = 4L
68/4 = L
17 = L <====length (L) = 17 inches
W = L - 6
W = 17 - 6
W = 11 <== width (W) = 11 inches
You could probably just put (1,0) but if not then my best guess would be (0.1,0)
Something is missing in this thing
An obtuse triangle would be formed. If you add all the angles, you get a total of more then 180 causing it to b obtuse.
Answer:
L^3=528 ; cube root both sides
L^3*1\3=528^1/3
L=8.1
