Find the area of an equilateral triangle in which each side has a length of 2cm.

Step 1. Area of equilateral triangle is where b is the base and h is the height. Draw a perpendicular line from one angle to the midpoint of the opposite side. Doing this forms a right triangle and bisected in half the opposite side.

Step 2. The base is 1/2 the side of the equilateral triangle or 2cm/2=1 cm.

Step 3. The height can be calculated using the Pythagorean Theorem which states that the sum of the squares of the legs of a right triangle (h and b) is equal to the hypotenuse squared or side s=2 cm.

Then,

Step 4. ANSWER: Area square centimeters.

I hope the above steps were helpful.
