Divide the perimeter by 3 to find the length of each of its 3 equal sides
Area = 0.5*side squared*sin(60 degrees)
Alternatively use Pythagoras' theorem to find its height then area is: 0.5*base*height
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 base is one third of the perimeter, half of the base times the height is the area.
That depends on what type of triangle is if the side given is equal to the perimeter divided by 3 then it is an equilateral triangle.
Find out what 1 side is and multiply by 3 to find perimeter
I need to know more about the triangle, such as one or 2 of the angles, whether it is isosceles or equilateral, or whether the lengths share a certain ratio. For example, a triangle of sides 8,8 and 5 (perimeter of 21) will surely have a different area as compared to a triangle of sides 7,7 and 7 (perimeter of 21 as well)
Find the area of an equilateral triangle if its perimeter is 18 ft
Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.
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 perimeter is 36 and the area is 144
The base is one third of the perimeter, half of the base times the height is the area.
Area of equilateral triangle: 0.5*7*7*sin(60 degrees) = 21.2 square inches
the answer is 32
Only if you also know the shape and proportions. An equilateral triangle, for example.
The perimeter of an equilateral triangle is calculated by multiplying the length of one side by 3, as all three sides of an equilateral triangle are equal in length. Therefore, if the length of one side of the equilateral triangle is represented by "s," the perimeter would be 3s. This is because there are three sides in total that need to be added together to find the perimeter of the equilateral triangle.

If the triangle is equilateral, you simply divide the perimeter by three to find the length of each side. If the triangle is not equilateral, you will need more information to determine the length of each side.
