The area of a square is 3 less than the perimeter of the same square. What is the length of a side of the square?

Answer 1

s^2 = 4s -3

s^2 -4s +3 = 0

(s-3)(s-1) = 0

side of the square = 1 or 3

P = 4 or 12

A = 4-3=1 or 12-3 = 9

although this mixes up apples and oranges

the units differ, squared units and linear units
