. As we all know, half the base times the height of any triangle will give you its area. This section will focus on a particular type of triangle that has three congruent sides. We’ll be using only its lengths and not altitude to calculate the area. 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. Use our worksheets to practice! They include a variety of triangles in integer and decimal dimensions. Use the formula to calculate their area. Keep one step ahead of your peers and find the side length for the triangle from the area. Start with our free worksheet
