100 is your answer to your question
Answer:
The length is 11ft.
The width is 8ft.
Step-by-step explanation:
Hello!
Perimeter of a rectangle:
- P = perimeter
- l = length
- w = width
We know that the length is 5 ft less than twice the width, which can be expressed by the equation: l = 2w - 5. We can plug in 38 for "P".
We can substitute the equation for l, and solve for the width.
<h3>Solve for W</h3>
The width is 8. We can solve for the length by plugging it back into the equation l = 2w - 5
<h3>Solve for L</h3>
- l = 2w - 5
- l = 2(8) - 5
- l = 16 - 5
- l = 11
The length is 11.
The dimensions are 11 ft and 8 ft.

To find the answer you would do 3.14xr^2=?
When you are subtracting over zeroes, you may need to carry over. This being said, you may need to take some from a previous number and put it into a zero, and continue carrying over until you can do what you needed to do. If you don't know the place value of the zero in mind, you will not end up completing this correctly.
