What equation represents the perimeter of the rectangle?

• 2L + 2W = 23

• L + W = 23

• L - W = 23

• L * W = 23

What is the equation for the area of the rectangle?

• L + W = 33

• L * W = 33

• L - W = 33

• 2L + 2W = 33

What is the first equation derived from the problem statement?

• L * W = 23

• 2L + 2W = 23

• L + W = 23

• L - W = 23

What is the second equation derived from the problem statement?

• L * W = 33

• L + W = 33

• 2L + 2W = 33

• L - W = 33

How is the width expressed in terms of the length?

• W = L - 23/2

• W = 23/2 - L

• W = L + 23/2

• W = 23 - L

What type of equation is formed after substituting the width expression into the area equation?

• Linear equation

• Quadratic equation

• Cubic equation

• Exponential equation
