The perimeter is the sum of all sides. An equilateral triangle has three sides of equal length. So if one side is 5 inches, and we have three of these, we get a perimeter of 15 inches.

Suppose you know the perimeter and the height of an equilateral triangle explain how you would find the area of the triangle.?
The base is one third of the perimeter, half of the base times the height is the area.
If the base angles of a triangle are congruent then the triangle is isosceles?
It will be either isosceles or equilateral. It is equilateral if all of the angles are congruent.
An equilateral triangle with sides of length 5 has the same perimeter as an isosceles triangle with the base of length 3 are two equal sides of 6?
In effect what you are asking is "does 5 + 5 + 5 = 6 + 6 + 3?" which of course it does. Is it the word perimeter that caused confusion?
What is formula of perimeter n area of equilateral triangle?
Perimeter = Sum of the three sides i.e. a+b+c Area = 1/2bh or (bh)/2 "b" stands for base "h" stands for height
What is the perimeter and area of a equalateral triangle whoose base 6m and height is 4m?
This is not an equilateral triangle if height is 4 m the base is 6 m and by Pythagorean theorem the other sides are 5 m perimeter is 6 + 5 + 5 = 16m Area = base x height = 6 x 4 = 24 sq m

Find the perimeter of an equilateral triangle that has a base side of 4 inches?
4 inches x 3 sides = 12 inches for the perimeter.
What is the perimeter of an equilateral triangle with 3 cm?
it is a equilateral triangle and 3cm each side base times high divided by 2 so........... 3x3=9 divided by 2= 4.5 cm
If the base angles of a triangle are congruent then the triangle is isosceles?
It will be either isosceles or equilateral. It is equilateral if all of the angles are congruent.

Is it only in an isosceles triangle that the base angles are equal?
No. It need not be the base angles that are equal, it can be one of the base angles and the top angle (if the triangle is tipped over). Also, the base angle are equal in an equilateral triangle - although an equilateral triangle is a special kind of isosceles triangle.
What is the area of equilateral triangle with height is 20 and Base is 15?
An equilateral triangle with a height of 20 has a base of 23.1 (23.09401), not 15. If the base is 15 then the height will be 13 (12.99038).

This is not an equilateral triangle if height is 4 m the base is 6 m and by Pythagorean theorem the other sides are 5 m perimeter is 6 + 5 + 5 = 16m Area = base x height = 6 x 4 = 24 sq m
Can you work out the area of an equilateral triangle with a perimeter of XXVII inches giving details of your work?
XXVII = 27 An equilateral triangle with a perimeter of 27 inches has three equal sides of 9 inches. Area of a triangle = base times its perpendicular height divided by 2. An equilateral triangle can be considered as being two right angled triangles joined together. So by halving the length of the base we can find its height by using Pythagoras' Theorem: hypotenuse2 - base2 = height2 92-4.52 = 60.75 square inches. Square root of 60.75 = 7.794228634 inches. Area = 9x7.794228634/2 = 35.07402885 square inches. Therefore area of an equilateral triangle with a perimeter of 27 inches is 35.074 square inches correct to 3 decimal places.

If the base of an isosceles triangle is 11 and the perimeter is 39 what is the length of a leg?
If the base of an isosceles triangle is 11 and its perimeter is 39, then it has a height of 12.87.
