\log_{10} (3y+2) - 1 =  \log_{10}(y-4)\\\\\implies \log_{10} (3y+2) - \log_{10} 10 = \log_{10} (y-4)\\\\\implies \log_{10} \left( \dfrac{3y+2}{10} \right) = \log_{10} (y-4)\\\\\implies \dfrac{3y+2}{10} = y-4\\\\\implies 3y+2 = 10y-40\\\\\implies 10y-3y = 40+2\\\\\implies 7y = 42\\\\\implies y = \dfrac{42}7\\\\\implies y = 6

48 cm. You have 16 units and know that 2 of them equal 6 cm. So you can either divide 16 by 2 and multiply by 6 or notice that each square is worth 3 cm and multiply 16 by 3 to get 48.
