One side of the triangle is 7 cm 2 8 cm and 3 4 cm larger than the second side find the perimeter of the triangle.

Initially, remember that the perimeter is the sum of all three sides of a triangular shape. And in order to calculate the perimeter of a triangle, we need to know the length of all three sides.

Therefore, we first calculate the length of the 3 sides of the triangular figure:

8 cm + 4 cm = 12 cm – the length of the 3 sides of the triangle.

Next, we calculate the perimeter, denoting it with a capital letter P.

P = 7 cm + 8 cm + 12 cm = 15 cm + 12 cm = 27 cm – constitutes the perimeter of the triangle.

To summarize: the perimeter of a triangular figure is 27 cm.
