Side length is about 12 units (11.99963) given an area of 62.35

The side length is 15.2 (15.19671) inches.

The length of the third side of an equilateral triangle is the same as the lengths of both of the other two sides.

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.

An equilateral triangle has three sides of the same length. Therefore, the length of each side of an equilateral triangle with a perimeter of 63 metres is equal to 63/3 = 21 metres.

To get the area of an equilateral triangle, you just need to know the length of one side. Multiply the length of one side by the square root of three and then divide the product by four, and you will get the area of the triangle.

Area of an equilateral triangle is s*(sqrt 3)/2, where s is the length of a side, or: area = s * 0.866666. . .
