How Do You Figure Square Feet Of A Triangle?
To calculate the area of a triangle using the known lengths of the three sides, use Heron’s formula. You do not need to know or measure the triangle’s angles when using this formula. Measure sides of the triangle. For example, let’s say those lengths are 3.2, 4.5 and 6 inches. Calculate the perimeter of the triangle, which is the sum of all three sides. In our example, the perimeter is 3.2 + 4.5 + 6 = 13.7 inches. Divide the triangle perimeter by 2; the resulting value is commonly referred to as a semiperimeter. In our example, the semiperimeter is 13.7 / 2 = 6.85 inches. Calculate the difference between the semiperimeter and the triangle’s first side. In the example, this difference is 6.85 – 3.2 = 3.65. Calculate the difference between the semiperimeter and the triangle’s second side. In the example, this difference is 6.85 – 4.5 = 2.35. Calculate the difference between the semiperimeter and the triangle’s third side. In the example, this difference is 6.85 – 6 = 0.85. Multiply the s
