Solution

Length of red stick $= 2 r$
Length of blue stick $= b$
Total no.of red stick $= 18$
Total no.of blue stick $= 6$
Therefore, total length of stick $= 18 r + 6 b = 6 (3 r + b)$

A triangle is made up of $ 2$ red sticks and $ 1$ blue stick. The length of a red stick is given by $ r$ and that of a blue stick is given by $ b$. Using this information, write an expression for the total length of sticks in the pattern given:

Length of red stick=2rLength of blue stick =bTotal no.of red stick=18Total no.of blue stick=6Therefore, total length of stick =18r+6b=6(3r+b)

Length of red stick $= 2 r$
Length of blue stick $= b$
Total no.of red stick $= 18$
Total no.of blue stick $= 6$
Therefore, total length of stick $= 18 r + 6 b = 6 (3 r + b)$
