Find the perimeter of a triangle where one side is 3 cm , one side is 9 cm and one side is 12 cm
To find the perimeter of a triangle, we need to sum the lengths of all three sides. Therefore, the perimeter of the triangle is 3 cm + 9 cm + 12 cm = 24 cm.
To find the perimeter of a triangle, you need to add the lengths of all three sides.
Given that the lengths of the sides are 3 cm, 9 cm, and 12 cm, you simply add them together:
Perimeter = 3 cm + 9 cm + 12 cm
Perimeter = 24 cm
So, the perimeter of the triangle is 24 cm.
To find the perimeter of a triangle, you need to add up the lengths of all three sides. In this case, the lengths of the three sides are given as 3 cm, 9 cm, and 12 cm.
To find the perimeter, simply add up these three lengths:
Perimeter = 3 cm + 9 cm + 12 cm
Performing the addition:
Perimeter = 24 cm
So, the perimeter of the triangle is 24 cm.
