Question

The length of a rectangle is four times its width. If the area of the rectangle is less than 100 square meters, what is the greatest width of the rectangle?


4w + w < 100
4 + 4w < 100
4w < 100
4w • w < 100

Answer 1

Just do the normal formula of the area but with l being 4w

Answer 2

would it be the third?

Answer 3

Well what's the normal formula?

Answer 4

im not sure

Answer 5

You don't the know the formula for the area of a rectangle?
