Answer 1

1rst side of the triangle - 1⅔ cm

2nd side of the triangle - 2¾cm

3rd side of the triangle - 23 cm (For now , considering the 3rd side of the triangle 23 cm as it is not properly mentioned in the question.

We know that , Perimeter of a triangle = Sum of all sides of that triangle

Here , Perimeter of triangle = 1⅔ cm + 2¾cm + 23 cm

= 5/3 + 11/4 + 23

= 20/12 + 33/12 + 253/12

= 306/12

= 25.5 cm

Hence , the perimeter of the triangle with 3 sides (1⅔ cm, 2¾cm and 23 cm) is 25.5 cm .
