Question

The sides of a triangle are in ratio 1 : 2 :3 if its perimeter is 72 cm , the length of its tallest side is ?

Answer 1

Step-by-step explanation:

1:2:3are the sides of triangle

then we know that the sum of the triangles=perimeter of triangle

so ,1*+2*+3*=72cm

so ,6*=72

*=72/6

*=12

now 1*=12

2*=24

3*=36,
