Arectangle’s width is one-fourth of its length. its area is 9 square units. the equation l(1/4l) = 9 can be used to find l, the length of the rectangle.

I see no actual question, but I'm assuming that you want to find the dimensions of the rectangle.

In general, the area of a rectangle with width and length is

In this case, we know that the width is one-fourth of its length, which means

If we plug this expression for w in the formula for the area, we get

We also know that the area is 9 squared units, so we have

If we multiply both sides by 4, we get

Consider the square root of both sides (we only accept the positive solution, since a negative length would make no sense:

So, the length is 6, and the width is one-fourth of 6, i.e.

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day
