Answer 2

Given : The sides of a triangle are 7/2 cm, 11/4cm,and 16/5cm

To find : Perimeter of triangle

Solution:

Sides of triangles are  7/2  cm , 11/4 cm  & 16/5 cm

Perimeter of Triangle  = Sum of Sides of Triangle

7/2  + 11/4  + 16/5

= 3.5  + 2.75  +  3.2

= 3.50 + 2.75 + 3.20

3.50

2.75

3.20

______

9.45

Perimeter of triangle  = 9.45  cm

or

7/2   +  11/4  + 16/5

LCM = 20

70/20 + 55/20  + 64/20

= (70 + 55 + 64)/20

= 189/20

Perimeter of triangle   = 189/20 cm  = 9.45  cm
