length is 20 and the width is 5

Step-by-step explanation:

so Area is 100

Area = width * length

legth = 4 * width

This means:

Area = width * 4 width =>  Area = 5 * width

We know that area is 100 so:

100 = 5 * width

that means width = 20, but wait didn't I say that the length is 20? Yes, remember we said length = 4 * width at the beginning, so length = 20.

Now we can easily calculate width as width is 4 times smaller than length, so:

width = 20/4 => 5

We can also test if this is correct by simply using the formula to calculate rectangle. So 5 * 20 = 100, correct!

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
