Question

The perimeter of a triangle is 26 centimeters. Side a of the triangle is 3 centimeters longer than side b. Side c is 1 centimeter shorter than twice side b. Find the length of each side.

Answer 1

a+b+c=26

a=b+3

c=2b-1

b+3+b+2b-1=26

4b=24

b=6 cm

a=6+3=9cm

c=2*6-1=11 cm

side *a* is 9 cm

side *b* is 6 cm

side *c* is 11 cm
