## Calculating an area measured in feet and inches

“How to calculate square feet”

Calculating square feet is unnecessarily complicated. This is because square feet is an area defined by feet and inches, which, unlike metric system, cannot be handled easily by simply multiplying two numbers with decimal points in between.

Then how do you calculate square feet of different shaped areas easily?

But if you want to learn how to calculate square feet of various shaped areas, read on.

## How to calculate square feet of a square area

To get square feet of a square area, you must square the length of the side of the square as follows:

Area = Length x Length

## How to calculate square feet of a rectangle area

To get square feet of a rectangular area, you must multiply the length and the width of the square as follows:

Area = Length x Width

## How to calculate square feet of a circular area

To get square feet of a circular area, you must multiply the constant Pi by the square of the Radius of the circle as follows:

Area = Pi x Radius * Radius

## How to calculate square feet of a triangular area

To get square feet of a triangular area, you must multiply the constant Pi by the square of the Radius of the circle as follows:

Area = 1/4 x square root ((x+y+z) x (y+z-x) x (z+x-y) x (x+y-z))
