Question 343455
P = 2L + 2W ___ 26 = 2L + 2W ___ 13 = L + W


A = L * W ___ 40 = L * W


you are looking for two numbers whose sum is 13 and whose product is 40
___ like 8 and 5




using equations


L = 13 - W


substituting ___ 40 = (13 - W) * W ___ 40 = 13W - W^2 ___ W^2 - 13W + 40 = 0


factoring ___ (W - 8)(W - 5) = 0


W - 8 = 0 ___ W = 8


W - 5 = 0 ___ W = 5


one dimension is 5 and the other is 8
