Area of an Equilateral Triangle Worksheets

We all know that half times base times the height of a triangle will give its area. In this section, though, we’re going to zero in on a special type of triangle with three congruent sides and learn to calculate its area with just its side lengths and no altitude measures. Wonder how? All it takes is an easy-to-remember simple formula, A = √3/4.a2, where ‘a’ denotes the side length of the triangle. Delve into practice with our printable worksheets for grade 8 and high school that present loads of triangles with integer and decimal dimensions! Apply the formula and calculate their area. Stay one step ahead of your peers by finding the side length of the triangle from the area as well! Get started with our free worksheet!
