You're finding the area of two shapes, a square, and a quarter of a circle.
So
A=As+Ac/4
A=Lw+πr²/4
A=(6)(6)+(3.14)(6²)/4
A=64.26 m²

Line LKJ is a straight line, so <LKJ =180°
<LKJ=<JKH+<HKL
180=78+4x+2
180=80+4x
100=4x
25=x
<HKL=4x+2
<HKL=4(25)+2
<HKL=102°
It's x>2. I hope this helps you out.
C I'm pretty sure , it says I need more words so I'm just gonna keep typing
