Answer:

Length= 20

Width= 4

Step-by-step explanation:

First, you can turn this into an equation:

Length= L

width= w

So L=5w

And using the area formula for rectangles, we get L*w=80.

Now, to solve, we only need to substitute 5w into L.

Now we have 5w^2=80. We divide by 5 on both sides to get w^2=16.

We take the square root of both sides. since the length and width of an rectangle cannot be negative, we are left with only w=4.

So plugging back in, we get L=20.

To check, 20*4=80.
