Answer: 7.5"
Step-by-step explanation:
First, take away the extra 5" on the longer side lengths
40-5-5=30
Then divide by 4 to get the width
30/4=7.5
This works because if you took the 7.5" and added back the 5 inches, it makes 12.5. Then add all 4 sides together, you get 40.
7.5+7.5+12.5+12.5=
Answer:
W = 7.5 in
We'll use the formula for the perimeter of a rectangle: P = 2W + 2L.
Here, L = W + 5, so P = 2W + 2L becomes:
P = 2W + 2(W + 5), and this equals 40 in.
Thus we have the equation in W (the desired variable) as follows:
2W + 2(W + 5) = 40 in, or 4W + 10 = 40.
Then 4W = 30, and W = 7.5 in.
