Bianca calculated the height of the equilateral triangle
with side lengths of 10
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
units.
The perimeter of the equilateral triangle is units.
Therefore, the area of the equilateral triangle is
vor approximately 43.5 units
The calculated areas are
tan(30) =
n = 8.7
rebo
Then, she used the formula for area of a triangle to
approximate its area, as shown below.
A = 20
= (10)(8.7)
= 43.5 units?
