b= 61.85cm

The solution is attached

Answer 2

$= > {(3a)}^{2} = {36}^{2} + {27}^{2} \\ \\ = > 9 {a}^{2} = 1296 + 729 \\ \\ = > 9{a}^{2} = 2025 \\ \\ = > {a}^{2} = 225 \\ \\ = > {a} = 15 \: cm \\ \\ now \: \\ 3a = 3 \times 15 = 45 \: cm$

$again \\ = > {b}^{2} = {60}^{2} + {15}^{2} \\ \\ = > {b}^{2} = 3600 + 225 \\ \\ = > {b}^{2} = 3825 \\ \\ = > {b} = 61.85 \: cm$
