Separate the root expression into the two numbers you found as factors, with each number now under its own square root symbol. For example, sqrt(12) = sqrt(4) times sqrt(3). 3) Keep simplifying. The square root of a perfect square becomes just a number, without theradical square root symbol.

Use Pythagoras theorem
${(6 + 3)}^{2} + {x}^{2} = {15}^{2} \\ {x}^{2} = 144 \\ x = 12$
Two triangles are similar
$\frac{6}{9} = \frac{y}{12} \\ y = 8$
(6+3)*12/2 - 6*8 /2 = 30
