Area = 4*1.75 = 7 square inches
1 inch by 9 inches = 9 square inches = 0.0625 square feet = 1/16 square foot
The area of a 3-inch square is: 9 square inches.
The area of a circle with a diameter of 4.75 is: 17.72 square units.
Given the information in the question, there is no need for any inequality. the flat surface can be described as an equality. Outer diameter = one and a half inches => outer radius = 0.75 inches. Inner diameter = three fourths inches => inner radius = 0.375 inches. Area = pi*(0.752 - 0.3752) square inches. So one possible set of inequalities is 0 < area < 1,000,000,000 sq inches!
There are many different triangles that have an area of three square inches, here's one way to draw one: Draw a rectangle whose area is six square inches (or imagine what one's dimensions would be, e.g. 6x1 or 3x2) and cut it in half diagonally to make a right triangle that has an area of three square inches.
3 inches, because the square root of nine is three
Three square feet would cover one square yard or 36 square inches.
--> 2 x 22, Area = 44 square inches --> 6 x 18, Area = 108 square inches --> 12 x 12, Area = 144 square inches
A square with a side length of 16 inches has an area of 256 square inches.
If the perimeter of a square is 28 inches the area is: 49 square inches.
Area of square: 324 square inches Perimeter of square: 72 inches
