Length: 12
Width: 4 since 12x4=48 and length is 3 times as long as it is wide.
3 3/4 =3.75
20.25 divide 3.75 = 5.4
one pound of candy costs 5.40
Use Pythagorean theorem
a^2 + b^2 = c^2
Plug in the info
b = 53, a = 41
41^2 + 53^2 = c^2
1681 + 2809 = c^2
c^2 = 4490
Squareroot of 4490 = 67.007
Perimeter = adding all sides
53m + 41m + 67.01m = 161.01 m
Solution: 161.01 meters
Y = -4x +5 should be right!
