Perimeter of Triangle Solution

Follow our step by step solution on how to calculate Perimeter of Triangle?

FIRST Step Consider the formula

P = S a + S b + S c

Next Step Substitute values of Variables

∴

P = 10m + 14m + 20m

Next Step Prepare to Evaluate

∴

P = 10 + 14 + 20

LAST Step Evaluate

∴

P = 44m
