Question 92
Perimeter of a triangle is found by using the formula p = a + b + c, where a, b and c are the sides of the triangle. Write the rule that is expressed by this formula in words.
Given, perimeter of the triangle p = a + b + c.
a, b and c are the lengths of sides of the given triangle.
∴ The given formula can be written as follows:
The perimeter of a triangle is equal to the sum of lengths of all three sides of the triangle.
