We use the law of Cosines to find b=AC opposite B
We know all the sides of triangle ABM so we can use the law of Cosines, this time to solve for
Substituting,
Answer: AC=√39
P=2l+2w
120=2(2w)+(2w
120=4w+2w
120=6w
w=20
120=2(20)+2(l)
120=40+2l
80=2l
l=40
Length is 40 and width is 20 feet
hope this helps:)
