Q
Q: What is the area of an equilateral triangle with side length 'a'?
Solution:
The area of an equilateral triangle is given by the formula (√3/4)a².
Steps: 4
Show Steps
Step 1: Understand that an equilateral triangle has all three sides of equal length, which we call 'a'.
Step 2: Recall the formula for the area of an equilateral triangle, which is (√3/4) * a².
Step 3: To find the area, you need to square the side length 'a'. This means you multiply 'a' by itself (a * a).
Step 4: Multiply the result from Step 3 by (√3/4). This gives you the area of the triangle.
