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.
It is a right angle triangle with an hypotenuse of 39 and sides of 36 and 15. Area of triangle is 0.5*36*15 = 270 square units
Equilateral triangles have all sides the same length, and to get the perimeter, you add all the side lengths. 15+15+15=45
The figure is a triangle. That means it has 3 sides. The triangle is "equilateral". That means all three sides have the same length. One side is 5 cm. That means each of the other 2 sides is also 5 cm. So the perimeter is (5 + 5 + 5) = 15 cm.
Height in inches = XV=15 Area of a triangle = base length times perpendicular height divided by 2 An equilateral triangle has three equal sides with three equal interior angles of 60o An equilateral triangle can be considered as being two right angled triangles joined together. So we can make use of trigonometry to find the base length: opposite/tangent = adjacent length of the right angled triangle 15/tangent 60o = 8.660254038 inches Base length of the equilateral triangle = 8.660254038*2 = 17.32050808 inches Area = 17.32050808*15/2 = 129.9038106 square inches Therefore the area of the equilateral triangle is 130 square inches which is correct to three significant figures.

a equilateral triangle has 3 sides that each equal 15 cm
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).
1 triangle = 3 sides, no matter what kind of triangle it is 5 triangles = 3 sides each = 15 sides

Length of a side of an equilateral triangle : Perimeter = 1 : 3 For example, if the length of the sides of an equilateral triangle were 5cm each, then perimeter would be three times that much - 15cm. 5 : 15 is the same as 1 : 3 when simplified.

If all 3 sides each have a length of 15½ inches, it would be called an Equilateral Triangle
Yes 5+5+5 = 15 6+6+3 = 15
