The total height of 2 boys: \(131.6\cdot2=263.2\left(cm\right)\)
The total height of 4 girls: \(128.3\cdot4=513.2\left(cm\right)\)
The total height of all children: \(263.2+513.2=776.4\left(cm\right)\)
All children: \(2+4=6\left(children\right)\)
The average height of all children: \(\dfrac{776.4}{6}=129.4\left(cm\right)\)
