Question

A wood board is 156 cm long is cut into 3 parts. The two longer parts are the same length and are 15c loner than the shortest part. How long are the three parts.

Answer 1

Step-by-step explanation:

Let the shortest part=S

The other two parts=S + 15

S + 2[S + 15] =156

S + 2S + 30 =156

3S=156 - 30 =126 divide both sides by 3

S=126/3

S=42 cm-the shortest wood board

42+15=57cm-the two other wood boards, so that:

42 + 57 + 57 =156 cm
