The length of a rectangle is twice its width. the perimeter of the rectangle is 126 feet.

Hey!

Step 1. The perimeter P means adding up all the four sides of a rectangle.

Step 2. Let w be the width.

Step 3. Let 2w be the length

Step 4. Then, P=w+w+2w+2w=126.

Step 5. Solving yields the following steps

w=21

Hope this helps!

Hey there! Welcome to Let's solve this together. :)

We can write this as a system of equations. We will have L be the length, and w be the width. We know that the formula for perimeter is 2L+2w=P, so let's plug in our numbers to make a system.

L=2w

2L+2w=126

As you can see, we have a value for L in terms of w. We can substitute this L-value into the second equation, and solve for w.

2(2w)+2w=126

4w+2w=126

6w=126

w=21

Now, we can plug our w-value into the first equation to find L.

L=2(21)

L=42

Therefore, our dimensions are below.

Length: 42 feet

Width: 21 feet

I hope this helps!

he kicked it up? is this the answer ?

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
