What is the area of an equilateral triangle with an apothem of 5cm?

5.7735 cm is the length of a side so 1/2 x base x Height should give you an answer.
Remember, the apothem makes two mirrored 30 60 right triangles...Pythagoras will tell you how to find the hypotenuse...that will be the unknown side of the equilateral.

Calculate area of a triangle?
Area of a triangle = 1/2 (Base x Height) Example: Width 13cm, Height 5cm, Base 12cm then; Area=1/2(12cm x 5cm) Area=6cm x 5cm Area=30cm2
What are some examples of scalen triangles?
A scalene triangle is a triangle that does not have a right angle in it (i.e. not a right angled triangle) and does not have two (or three) sides with the same length (i.e. not an isosceles triangle or an equilateral triangle). An example is a triangle with sides of length 4cm, 5cm and 6cm.

Does 5cm 5cm 5cm make a triangle?
5cm, 5cm, and 5cm could represent the lengths of the sides of an equilateral triangle, or might indicate the length, width, and height of a cube.

What is the ratio of the length of a side of an equilateral triangle to its perimeter?
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. 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.
