I'm guessing you meant the length is 5 in. shorter than the width.

I'll use L, W, and A to represent length, width, and area, respectively.

We know the area of a table, which is a rectangle, is given by A = L * W.
We also know that L = W - 5.
And then W = W, pretty much.


So, given any width W, we can find L and A.

Width is W
Length is L = W - 5
Area is A = L * W, but let's replace L with (W - 5).
A = (W - 5) * W
A = W^2 - 5W

Answer:

Some of the signs and symptoms of sleep disorders include excessive daytime sleepiness, irregular breathing or increased movement during sleep. Other signs and symptoms include an irregular sleep and wake cycle and difficulty falling asleep. Some common types of sleep disorders include:

Insomnia, in which you have difficulty falling asleep or staying asleep throughout the night.

Sleep apnea, in which you experience abnormal patterns in breathing while you are asleep. There are several types of sleep apnea.

Restless legs syndrome (RLS), a type of sleep movement disorder. Restless legs syndrome, also called Willis-Ekbom disease, causes an uncomfortable sensation and an urge to move the legs while you try to fall asleep.

Narcolepsy, a condition characterized by extreme sleepiness during the day and falling asleep suddenly during the day.

There are many ways to help diagnose sleep disorders. Doctors can usually treat most sleep disorders effectively once they're correctly diagnosed.
