Question

What is the perimeter of an equilateral tringle given one side x+10

Answer 1

Perimeter = 3 x+ 30  or  3 ( x+10)

Step-by-step explanation:

From the definition of equilateral triangle we know that all sides and all angles of such triangle are equal.

Thus, the perimeter of the triangle will be the sum of all sides.

Since, we are provided with one side e.g. x+10 and we know triangle has three sides

Perimeter of equilateral triangle =  (x+10)+(x+10)+(x+10)

Perimeter = 3 x+ 30 or 3 ( x+10)
