Use this calculator to easily calculate the area of a triangle, given its base and height in any metric: mm, cm, meters, km, inches, feet, yards, miles, etc. Fill in base and height, then Calculate to display the triangle’s area using ½ × base × height.
Measuring a Roof Section
Imagine a triangular roof panel that has a base of 12 feet and a height of 6 feet. The formula for the area of a triangle is A = ½ × base × height. Substituting the values, A = ½ × 12 × 6 = 36 ft². The calculator provides this result instantly, helping you plan roofing materials.
Understanding the Formula
The area of a triangle is always half the product of its base and height. Mathematically, A = ½ × b × h. For example, if a triangle has a base of 10 meters and a height of 8 meters, A = ½ × 10 × 8 = 40 m². The calculator applies this formula automatically once values are entered.
Building with Triangular Plots
Some pieces of land are shaped like triangles. Suppose you buy a triangular plot with a base of 50 feet and a height of 40 feet. The area is A = ½ × 50 × 40 = 1000 ft². Using the calculator avoids guesswork and ensures you know the actual size before construction begins.
Checking School Assignments
Students often face questions like: “Find the area of a triangle with base 9 cm and height 7 cm.” By formula, A = ½ × 9 × 7 = 31.5 cm². Entering these numbers into the triangle calculator confirms the answer, making it a simple tool for verifying classroom problems and practice work.
Handling Mixed Units
If the base is measured in meters and the height in centimeters, the triangle calculator automatically adjusts the values. For example, base = 3 m and height = 150 cm. The calculator converts 150 cm to 1.5 m, then A = ½ × 3 × 1.5 = 2.25 m². This prevents errors when working with different units.
Comparing Triangular Areas
Suppose you want to compare two triangular gardens. Garden A has a base of 20 feet and a height of 15 feet, giving an area of 150 ft². Garden B has a base of 25 feet and a height of 10 feet, also 125 ft². The calculator makes such comparisons quick, showing which shape has more space.
Use area calculator for all types of general calculations related to area as per different needs.
