The total length of the two plank is 4x cm
Addition in maths is a process of combining two or more numbers.
Given that, A carpenter has two planks of wood. One plank is x cm long, the other plank is 3x cm long.
To find the total of the length of the plank, we will have to add their lengths,
Therefore, total length = 3x+x = 4x
Hence, the total length of the two plank is 4x cm
