Question

Find the perimeter of a triangle whose sides are 5 1/2 cm, 7 3/5 cm, and 3 1/4 Cm respectively.

Answer 1

Answer:

perimeter of triangle= sum of all sides

perimeter of triangle = 327/20 cm

Answer 2

Answer:

The perimeter of the triangle whose sides are $5\frac{1}{2}$ cm, $7\frac{3}{5}$ cm, and $3\frac{1}{4}$ cm is $16.35cm$

Step-by-step explanation:

Given:

sides of the triangle are $5\frac{1}{2}$ cm, $7\frac{3}{5}$ cm, and $3\frac{1}{4}$ cm

We need to find the perimeter of the triangle.

We know that

The perimeter of the triangle = Sum of all sides of the triangle

$P=5\frac{1}{2}+7\frac{3}{5} +3\frac{1}{4}\\\\P=\frac{11}{2} +\frac{38}{5} +\frac{13}{4}$

$P=\frac{110+152+65}{20} \\\\P=\frac{327}{20} \\\\P=16.35$
