Question

The length of three sides of a triangle is 14cm, 17cm and 25cm. find the perimeter of the triangle.

Answer 1

Hint: we have given length of three sides of triangle plug these value in the formula of the perimeter of triangle\[ = \]$\left( {a + b + c} \right)$\[cm\]where a, b, c are sides of the triangle and we will get the required answer.

Complete step by step solution:
Given: sides of the triangle are 14, 17 and 25 cm.
Let a=14cm
b=17cm
and c=25cm
Perimeter of triangle\[ = \]$\left( {a + b + c} \right)$\[cm\]; where a, b, c are sides of triangle
On substituting the values of a, b and c we get,
$ = \left( {14 + 17 + 25} \right)$cm$ = 56cm$
$ = 56cm$
Hence, the perimeter of the triangle is 56cm.

Note: The term perimeter means a path that surrounds an area. It refers to the total length of sides or edges of a polygon. Also, check the length of all the sides of the triangle should be in the same unit if not then convert it into the same unit.
