If Mark makes a circle, that circle would have a circumference of 12 inches. The formula for circumference is pi times diameter, so the circumference divided by pi will give you the diameter of 3.82 inches. Divide this by 2 to get the radius of 1.91 inches. Area of a circle is pi times the radius squared. 1.91 squared is 3.6481. Multiply this by pi to get 11.46 square inches of area inside the circle. A circle is always the most efficient use of space possible given a fixed perimeter. If Mark makes a square with equal sides where all sides are 3 inches, the area would be 9 square inches. 3 X 3 = 9

The square's area is 36 in2 while the rectangle's is 32. So the square has the greater area.
Any length greater than six.
105 = 7 x 15.

The square's area is 36 in2 while the rectangle's is 32. So the square has the greater area.
The length of a rectangle is 8 inches. The width of the rectangle is 4 inches. What is the perimeter of the rectangle in inches?
Any length greater than six.
The dimensions are: length = 15 inches and width = 7 inches Check: 15*7 = 105 square inches
105 = 7 x 15.
The area of a rectangle is 56.25 square inches. The length of the rectangle is12.5 inches what is the width
Length 7 inches and width 4 inches because 7*4 = 28 square inches
To maximize the area of a rectangle with a fixed perimeter, the rectangle should be a square. Given 14 inches of string, the perimeter ( P ) is 14, so each side of the square would be ( \frac{14}{4} = 3.5 ) inches. The area ( A ) of the square is then ( A = 3.5 \times 3.5 = 12.25 ) square inches. Thus, the largest rectangular area that can be enclosed is 12.25 square inches.
The area of Joseph’s rectangular homework desk is 1,008 square inches. If the length of his desk is 42 inches, how wide is his desk?
15 x 7 = 105...
