Try to do the others on your own using the information I gave you.
In one dimensions (i.e. with standard numbers and not points with more coordinates) the midpoint is the same as the average.
The average of two numbers is their sum divided by two.
So, we have -4+20=16. Divide this by two to get 8.
Answer:
1) Known information:
- The perimeter.
-
- The formula of the perimeter of the rectangle:
Unknown information:
- The value of the widht.
- The value of the length.
2) Equation:
3)
Step-by-step explanation:
1. The problem gives you the perimeter, the formula of the perimeter of a rectangle and says that the width of a rectangle is 3 feet shorter than its length (), but does not give the value of the widht and the value of the lenght.
2. Based on the information given, you can write the following equation:
Where is the lenght and is the width.
Substitute into the equation above, then you have:
3. Solve for the lenght:
4. Know you can calculate the width:
5. Therefore, the length is 134 feet and the widht is 131 feet.
