a=1/2bh b=h=6 a=.5*6*6 a=18
Base times height and divided by 2.
You find the height by using Pythagoras' theorem and then 0.5*base*height = area.
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.
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

For an equilateral triangle with side length a, area = (a²√3)/4, which for a= 6cm is 15.6 cm² [rounded to 1 decimal place]
Find the area of an equilateral triangle if its perimeter is 18 ft
a=1/2bh b=h=6 a=.5*6*6 a=18
Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.
Area of an equlateral triangle = 0.5*side2*sin(60)
62.354 units squared.
Area of equilateral triangle: 0.5*7*7*sin(60 degrees) = 21.2 square inches
Base times height and divided by 2.
An equilateral triangle has three sides of exactly the same length. Therefore, if one side of the triangle is equal to 12 yards, then the perimeter of the triangle is equal to 12 x 3 = 36 yards.
Given this area, the sides measure 52.92734 cm
