Area of the rectangle: {base times height}
4cm x 8cm = 32cm^2

Area of the triangle: {base times height divided by two}
(4cm x 11cm) : 2 = 22cm^2

Total area = 22cm^2 + 32cm^2 = 54cm^2

Can someone answer with steps and explanation? Thanks.

Answer:

BC=9\sqrt{3}\approx15.59\text{ units}

Step-by-step explanation:

Since Segment BOA is a diameter:

m\angle ACB=90

Arc Ac and Arc CB are in a ratio of two to four. Since Segment BOA is a diameter, Arc ACB measures 180°. Letting the unknown value be <em>x</em>, we can write that:

2x+4x=180

Hence:

x=30

Thus, Arc CB = 120°. By the Inscribed Angle Theorem:

\displaystyle m\angle A=\frac{1}{2}\left(\stackrel{\frown}{CB}\right)=\frac{1}{2}\left(120)=60

Therefore, ΔABC is a 30-60-90 triangle. Its sides are in the ratios shown in the image below.

Since AC is opposite from the 30° triangle, let AC = <em>a</em>.

We are given that AC = 9. Hence, <em>a</em> = 9.

BC is opposite from the 60° angle and it is given by <em>a</em>√3. Therefore:

BC=9\sqrt{3}\approx15.59\text{ units}
