Question

The perimeter of a triangle is 76cm. Side a of the triangle is twice as long as side b. Side c is 1cm longer than side a. Find the length of each side.

Answer 1

2b + b + 2b +1 = 76 cm
5b = 75 cm
b = 15 cm
a = 30 cm
b = 15 cm
c = 31 cm

Answer 2

How did you find the individual length of each side

Answer 3

By being clever ;)

Answer 4

a = 2b = 2 * 15 = 30
b = 15
c = a +1 = 2b+1 = 30 +1 = 31

Answer 5
