A triangle is a three-sided polygon, existing in various lengths and forms. To calculate square footage of a triangular shape, you need to calculate the area of the triangle with feet as the unit of measurement.
Know MoreMeasure the length of the base and the height of the triangle. The base can be any side, but make sure it is consistent throughout the entire process. The height of the triangle is simply the distance from the opposite corner to the base. When measuring height, your measurement should be at a 90-degree angle from the base. Also ensure that you are measuring in feet. This guarantees that your area ends up being measured in square footage.
The equation for calculating the area of a triangle is ½ multiplied by the base multiplied by the height. Take the base and height measurements in Step 1 and multiply them together, and then divide the product of these measurements by 2.
Do the math and solve the equation. If you perform this calculation correctly, you should have the square footage of your triangle. To check your work, divide your answer by two variables. If your answer was correct, this number should be your third variable.
Find the area of a triangle using the formula (b x h)/2. You need the value of "b," or base, and "h," or height.
Full Answer >The formula for the area of any triangle equals 1/2 the base times the height. For a right triangle, this is easy to remember ,since a right triangle is half of a rectangle on one side of its diagonal, and the area of a rectangle equals base times height.
Full Answer >To find the height of a scalene triangle, the formula for the area of a triangle is necessary. The equation is area = 1/2hb, where h is the height and b is the base. However, before using this formula, other calculations are required.
Full Answer >To find the perimeter of a trapezoid, add up the length of each of the sides of the shape. Use the equation P = a + b + c + d.
