Let the length be x+4 and the width be x:-
Form a quadratic equation: (x+4)*x = 45 => x^2 +4x -45 = 0
Solving the equation: x has a positive value of 5
Therefore length is 5+4 = 9 feet and width = 5 feet
Check: 9 times 5 = 45 square feet

2_x_ + 2(x – 4) = 45
What is the equation used for calculating the area of a square rectangle?
The area of a square (the word "rectangle" is redundant), with sides of length s units, is s^2 square units.
Does a square and a rectangle has equal length?
A square (a by a) and a rectangle (a by b) can have sides that are of equal length.
What is the equation used for calculating the area of a square or a rectangle?
Area=Length x width or A= L x W
Can a square be a rectangle but can a rectangle be a square?
Yes.A square is a special kind of rectangle, one with all sides of equal length. So all square are rectangles.All rectangles are not squares, some (most) have two sides longer than the other two.

Is it generally accepted that the length of a rectangle is longer side?
No. length is usually the bottom. Furthermore, a rectangle doesn't necessarily have a longer side. A rectangle simply needs 4 right angles. Therefore a square is a rectangle, yet has no longer side.

What is the different between the square and rectangle?
square has four equal sides a rectangle has two sides of one length and two of another and the rectangle is longer and thinner
The length of a rectangle is 5 feet longer than its width The area of the rectangle is 374 square feet What are the dimensions of the rectangle?
17 and 22
The area of a rectangle is 63 square feet the length is two feet longer than the width what is the width of the rectangle?
Area of a rectangle is length times width, therefore if the length is two feet longer than the width then the length is 9 and the width is 7, when they are multiplied you get 63
