The shorter piece of wire is 8 cm long.
We are given that a wire is 19 cm long.
We have cut the wire into two pieces.
We are also given that the longer piece of wire is 3 cm longer than the shorter piece.
Lest the shorter piece of wire be x cm
Longer piece = x + 3 cm.
So, the equation formed will be:
x + x + 3 cm = 19 m
2 x + 3 cm = 19 cm
2 x cm = 19 cm - 3 cm
2 x cm = 16 cm
x = 16 / 2 cm
x = 8 cm.
Therefore, the shorter piece of wire is 8 cm long.
