We are asked to solve for the width "x" in the given problem. To visualize the problem, see attached drawing.
We have the area of the swimming pool such as:
Area SP = l x w
Area SP = 10 * 16
Area SP = 160 feet2
Area of the swimming pool plus the sidewalk with uniform width:
Area SP + SW = (10 + x) * (16 + x)
160 + 155 = 160 + 10x + 16x + x2
160 -160 + 155 = 26x + x2
155 = 26 x + x2
x2 + 26x -155= 0
Solving for x, we need to use quadratic formula and the answer is 5 feet.
The value of x is <span>5 feet. </span>

Answer: 65.5 inches of the box is empty.
Step-by-step explanation:
Given : Diamter of circular pizza =10 inches
Then, radius =
Area of circle =
Area of pizza =
Side of square = 12 inches
Area of square = side x side.
Area of square = 12 x 12 = 144sq. inches.
Area of box empty = Area of square - Area of pizza
= 144-78.5 sq. inches
= 65.5 inches
Hence, 65.5 inches of the box is empty.
