work:
9.25/2.5 = $3.70.
let's find the unit rates of the others!
16.28/4.4 = $3.70
12/3.2 = $3.75
10.50/2.8= $3.75
only the first one has the same untit rate, the rest are different!
hope this helps :D
width (w): x
Length (L): x + 1
Perimeter = 2(L) + 2(w)
14 = 2(x + 1) + 2(x)
14 = 2x + 2 + 2x
14 = 4x + 2
12 = 4x
3 = x
Length: x + 1 = (3) + 1 = 4
Answer: width = 3, length = 4
