The perimeter of a rectangular piece of land is 180 meters.
The length of the rectangle is 36 meters.
2(L + W) = 180, L + W = 90, W = 90 - 36 = 54
The width of the rectangle is 54 meters.
(Length is normally longer than the width!)

Perimeter = P
Length = L
Width = W
a) P = 2(L+W)
b) 180 = 2(36 + W)
90 = 36+W
W = 90-36
W = 54 meters
Interesting. Normally the longer dimension is called the "length" and the shorter the "width".
