Please help.
This is very hard to me.

Width is 20 inches.

Length is 44 inches.

Step-by-step explanation:

Recall that the perimeter of a rectangle is given by the formula:

Where l is the length and w is the width.

We know that the length is 4 more than double the width. In other words, we can write an equation for l:

Let's substitute this into the above equation. So:

Combine like terms:

We are given that the perimeter is 128 (inches). So, substitute 128 for P and solve for w:

Divide both sides by 2. The right side cancels:

Subtract 4 from both sides:

Divide both sides by 3:

Therefore, our width is 20.

We can use the length formula we acquired previously to acquire length. We have:

Substitute 20 for w:

Multiply:

Add:

So, our length is 44.

And we width is 20.

And we're done!

12m

step-by-step explanation:

square root means have of a number so have of 3 is 1.5 then multiply it by 8 and you get your answer!
