Bianca calculated the height of the equilateral triangle with side lengths of 10. then, she used the formula for area of a triangle to approximate its area, as shown below. calculate the area of the equilateral triangle using the formula for area of a regular polygon, and compare it to bianca’s answer. the apothem, rounded to the nearest tenth, is . the perimeter of the equilateral triangle is . therefore, the area of the equilateral triangle , or approximately 43.5 units2. the calculated areas
