Question

The three sides of a triangle are 11/3 cm , 15/4 cm and 26/9 cm . find it's perimeter .​

Answer 1

☘︎Answer :-

$\sf\longmapsto \: \frac{371}{36}$

☘︎ Solution :-

• Given : Three sides are 11/3 cm , 15/4 cm and 26/9 cm
• To find : perimeter of the triangle

Perimeter of a triangle = Sum of the length of the three sides

perimeter of the given triangle = 11/3 + 15/4 + 26/9

• Make the denominator same by taking the LCM of the denominators .

( LCM of 3 , 4 and 9 is 36 )

$\sf\longmapsto \: \frac{132 \: + \: 135 \: + \: 104}{36} \: \: \:$

$\sf\longmapsto \: \frac{371}{36} \: cm \:$

♧ Therefore, the perimeter of a triangle is 371/36 cm
