Answer:
Step-by-step explanation:
Let's set up our equation. We know that rectangles have two pairs of equal sides. We are also given that one pair of those sides is 1 unit longer than the other pair. Finally, we are told that the perimeter is at <u>most</u> 60 meters. 'At most' tells me to set up an inequality.
I'm going to set up two equations to solve this problem. First, let be the longer side and
be the shorter side.
Next, because the sides are consecutive integers and is shorter, we can say that
.
We now have a system of equations. I will solve using substitution.
Substitute into the first equation.
Solve algebraically.
So, could be any integer between 0 (since distance cannot be negative) and 14.5, also written as
.
