Base times height and divided by 2.
The formula to calculate the area of a triangle is (base/2) x height... therefore the are of the triangle in this case is 18 square inches
the formula for finding the area of a triangle is: axb/2=______ so since its an equalateril triangle, every side is 6 so you do 6x6/2 which is 18
15.588 ft2 using the formula: (Sqrt(3)/4)×(side)²
It is: 0.5*length squared*(sin 60 degrees)
