Square Foot Calculator is used to calculate area or square of the given number. The number is in feet and/ or inches, therefore square of feet gives square footage. We can use it to find area of square, circle or triangle.
Square Footage = Square Feet = SqFt=ft. ft = ft2
Example 1: Find the square foot of the Carpet with length 4 feet and width 3 feet
Square foot of an object is the area. The solution to the problems will be
Carpet’s length = 4 feet and width = 3 feet. Since a carpet is rectangular, to find the square foot we will have
to multiply its length and its width.
Square Foot = area of carpet = Length x width = 4 ft x 3 ft = 12 ft2
Example 2: Find the square foot of the circle with diameter 5 feet.
Square foot of an object is the area.
Circle’s diameter = 5 feet, therefore circle’s radius r = 5/2 = 2.5 feet. Since a circle’s area is πr2, to find the
square foot = π x r x r
Square Foot = area of circle = π x r x r = π x 2.5 ft x2.5 ft = 3.14 x 2.5 x 2.5 = 19.625 ft2
