Sin 30 = 3/bl

1/2 = 3/bl

bl= 6



x/6 = cos30

x/6 =√3 / 2

x= 3 √3

3/bp = sin 45

3/bp = √2 /2
bp= 6/√2 =3√2

y/3√2 = cos 45

y/ 3√2 = √2/2

2y=6, y=3

pg= 10 - 3- 3√3 = 7-3√3


P1 = 3 * 3√3/2 = 4.5√3
P2=3* (7-3√3) = 21 -9√3
P3=3*3/2=4.5

P= 4.5√3 + 21 -9√3 + 4.5= 25.5 - 4.5√3
O= 10+6+7-3√3 +3√2 = 23-3√3 +3√2
