The length of a rectangle is 4 meters longer than the width. If the area is 22 square meters. find the rectangles dimensions. The width is what? The length is what?

The width is:

And the length is:

Step-by-step explanation:

Recall that the area of a rectangle is given by:

Where w is the width and l is the length.

We are given that the length of a rectangle is four meters longer than the width. Thus:

And we also know that the area of the rectangle is 22 square meteres.

Substitute:

Distribute and isolate the equation:

The equation isn't factorable, so we can instead use the quadratic formula:

In this case, a = 1, b = 4, and c = -22. Substitute:

Evaluate:

Thus, our two solutions are:

Since the width cannot be negative, we can ignore the second solution.

Since the length is four meters longer than the width:

Thus, the dimensions of the rectangle are:

Or, approximately 3.0990 by 7.0990.

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
