Square feet calculate the covered area by an object and the method to calculate the area of a square is: Square of the length of its side. For example if the length = 3 square foot then the answer is

Formula = length * length

=3x3 = 9

for rectangle the area is given by multiplying the length of the rectangle with its breadth. For example if the length = 5 square foot and breadth = 3 square foot then

Formula = length * breadth

=5x3 = 15 square feet

In case of a triangle the area can be found out by multiplying the base and height of the triangle and then dividing by 2.

For example if the base of the triangle = 4 square foot and height = 6 square foot

Formula = (Base * Height)/2

=(4x6)/2

=12 square feet
