Answer:
Length = 27.2
Width = 6.8
Step-by-step explanation:
P = L+L+W+W
68 = 4(L+L)+W+W
68 = 4(x+x)+x+x
68 = 4x+4x+x+x
68 = 10x
x = 6.8
L = 4x
L = 27.2
W = x
W = 6.8
68 = 27.2+27.2+6.8+6.8
68 = 68

Answer:
Step-by-step explanation:
You know the lengths of two sides and the angle between them, so use the Law of Cosines to find the third side.
x^2 = 10.5^2+ 5.4^2 -2(10.5)(5.4)cos20°
x ≈ 5.73 units
