Scott bought 54m of fencing to enclose a rectangular plot of land. The width of the rectangular plot is 12m. Assume Scott uses all the fencing. What is the length of the rectangular plot of land?
a) choose a variable to represent the length of the rectangular plot of land. Write an equation.
b) solve equation using the distributive property.

P = 2L + 2W
54 = 2L + 2(12)
54 = 2L + 24
30 = 2L
15 = L
