Answer 2

Answer:

The perimeter of triangle = $12\frac{1}{3}$ cm

Step-by-step explanation:

Given sides of triangle from figure

                  AB = $2 \frac{2}{5}$  =  $\frac{ 12}{5}$ cm    [ 5×2 +2 =12 ]

                  BC = 3 $\frac{1}{2}$ = $\frac{7}{2}$ cm       [ 3×2 +1 =7 ]

                  AC = $4\frac{1}3}$  = $\frac{13}{3}$ cm     [ 3×4 + 1 =13 ]    

perimeter of triangle =  AB +BC +AC

                                   =  $\frac{12}{5} +\frac{7}{2} +\frac{13}{3}$    

                                   =   $\frac{12(2)(3) + 7(5)(3) + 13(5)(2)}{5(3)(2)}$

                                   =  $\frac{ 72+ 105+ 130}{5(3)(2)}$ =$\frac{370}{30}$ = $\frac{37}{3}$

   $\frac{37}{3}$  is can be written as  $12 \frac{1}{3}$
