An equilateral triangle has a side length of 10 units. what is its area?

Area of equilateral triangle = 43.3 units^2

Step-by-step explanation:

An equilateral triangle is a triangle in which all three sides of triangle are equal.

So,Length = 10 units

Area of triangle =

                           =

                           =

                          =

So, Area of equilateral triangle = 43.3 units^2.

The answer is:

The area of the triangle is equal to  

To calculate the area of an equilateral triangle, we need to use the following formula:

Now, we are given an equilateral triangle, so we know that all of its sides are equal to 10 units.

So, calculating the area we have:
