Basic formula for square feet To calculate feet squared (or sq. ft. for short), determine the length and width of the area you are working with, measured in feet. Multiply the length by the width and you’ll have the square feet. Here’s a basic formula you can follow: Length (in ...
Square Feet Formula for Rectangles and Squares If the shape you're considering is a square or a rectangle, finding the area is as simple as multiplying length times width. When done in terms of feet, this formula comes in handy for everything from gauging the area of a lawn to calculatin...
3. Using Correct Measurements Take your measurement. Since you want to have an answer in square feet, you need to use feet as your basic unit for measurement. This means when you measure the radius of your circle, you need to convert the radius to feet. For instance if your radius measu...
Write the formula down. Use the formula πr2to find the area of a circle. To understand what the formula means, you need to understand the variables. Pi, written as π, approximately equals (22÷7), usually rounded to 3.14. Pi is a universal constant that shows up naturally in calcula...
Square feet are widely used to measure area in the United States and a few other countries. While an area defined by a triangle can be calculated in a number of ways, the Heron's Theorem (formula) allows you a straightforward computation of the triangle's area. All you need to know are...
2 Use the square footage formulaFor step 2, you're going to use the square footage formula: Length × Width = Area (in square feet) Note that the same formula applies if you measure in metric. In this case, the area will be expressed in square metres. ...
Calculate Square Footage Square footage = length (or height, for vertical surfaces) x width.That’s the basic formula to calculate square footage. Simple, right? Examples: Square footage of a floor 15 feet long and 10 feet wide = 15 times 10, or 150 square feet. Square footage of a wal...
Determining the square feet of a circular pool is the same as determining the area of a circle. Calculate the area of a pool so you'll know how much land a round pool will take up on your property. The formula for calculating the area of a circle is pi times radius squared. ...
