The length of the rectangle is 21 feet.

Step-by-step explanation:

A rectangle is 4-sided polygon where all interior angles are 90°.

The perimeter of a rectangle is the total distance around the outside of a rectangle and its given by

where is the length and is the width of the rectangle.

To find the length of the rectangle. First, we can write the relationship between the length and width as:

Next, substitute the above relation into the formula for the perimeter of a rectangle.

We know that the perimeter is 62 feet.

And we solve for the width.

We can now substitute  the width  into our formula for the relationship between  the length and width and calculate  the length.

The length of the rectangle is 21 feet.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
