    Answer: The length of pencil is 16 centimetres and length of crayons is 8 centimetres

    Step-by-step explanation:

    Let the length of crayon =x

    Length of a pencil =2x

    As according to question that the sum of their length is 24 centimetres

    So we have

    x+2x=24\\\\\Rightarrow 3x= 24 \\\\\Rightarrow x= \dfrac{24}{3} =8

    Therefore the length of crayon = 8 centimetres

    Length of pencil= 2x= 2\times x = 2\times 8 =16 centimetres

    Hence, the length of pencil is 16 centimetres and length of crayons is 8 centimetres
