The perimeter of a triangle is 51 centimeters. The lengths of its sides are consecutive odd integers. Find the lengths of all three sides

Since the lengths are consecutive odd numbers and the perimeter of the triangle is 51cms. Let x be the unknown length.

so 3x=51; x=17. now the sides can be 15cms, 17cms, 19cms.

check Add them up it is 51cms which is the perimeter and the consecutive odd numbers
