Question

find perimeter of a traingle (in cm) whose sides are 3.54 cm, 60mm and 48 mm.

Answer 1

Sides = 3.54 cm, 60mm, 48mm

Firstly we need to change mm into cm {or cm into mm}

60 mm = 60 / 10

= 6 cm

48mm = 48 / 10

= 4.8 cm

Perimeter of triangle = Sum of all the 3 sides

= 3.54 + 6 + 4.8

= 14.34 cm

OR

We can change cm to mm

=> 3.54 cm = 35.4 mm

Perimeter = 35.4 + 60 + 48

= 143.4 mm

Hope it helps☺

Answer 2

Answer:

60mm=60/10cm=6cm

48mm=48/10cm=4.8cm

3.54cm=3.54cm

now,

P=6+4.8+3.45

=14.25cm
