Question

find the perimeter of the adjacent figure in metre

Answer 1

AB=12/5 cm =2.4cm=0.024m
BC=7/2 cm =3.5cm =0.035m
CA=13/3 cm =4.4cm =0.044m
substitute this value in perimeter of triangle formula

Answer 2

Here is your solution

Given :-

$A \: triangle \: having \: sides \\ \: are \: \: 4 \frac{1}{3} \: , \: \: \: 2 \frac{2}{5} \: , \: \: 3 \frac{1}{2} \\ \\ to \: find \: perimeter \\ \: now \: we \: add \: the \: sides$
$= 4 \frac{1}{3} + 2 \frac{2}{5} + 3 \frac{1}{2} \\ \\ = \frac{13}{3} + \frac{12}{5} + \frac{7}{2} \\ \\ = \frac{130 + 72 + 105}{30} \\ \\ = \frac{307}{30} cm$
Now we change perimeter cm into m

$= \frac{307}{30} \div 100 \\ \\ = \frac{307}{30} \times \frac{1}{100} \\ \\ = \frac{307}{3000} \\ \\ = 0.10m$

Hope it helps you
