Square Foot Calculator

Online Tutoring Is The Easiest, Most Cost-Effective Way For Students To Get The Help They Need Whenever They Need It.

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
