Q.2: Find the height of an equilateral triangle whose side is 28 cm? Solution: Given, Side of the equilateral triangle, i.e. a = 28 cm We know, height of an equilateral triangle, i.e. h=3√a2 i.e. h=3√×282 i.e. h=143–√cm ...
Area formulas give us the sizes of everything from baking pans to house plans. Knowing how to use them is key. GRADIENT BACKGROUND/Shutterstock Key Takeaways The common formula for the area of a triangle is A = b × h / 2, where b is the base and h is the height. Other methods...
This formula is applicable to all types of triangles, whether it is a scalene triangle, an isosceles triangle, or an equilateral triangle. It should be remembered that the base and the height of a triangle are perpendicular to each other....
The area of equilateral triangle is the amount of space occupied by the triangle in a two-dimensional plane. We all know that an equilateral triangle is a triangle consisting of three equal sides and each of the three internal angles measuring 60 degrees. In an equilateral triangle, median, ...
