{\qquad\qquad\huge\underline{{\sf Answer}}}

Let's solve ~

Area of shaded region is equal to :

Area of rectangle - Area of two triangles ~

1. Area of rectangle :

\qquad \sf  \dashrightarrow \: length \times width

\qquad \sf  \dashrightarrow \: 20 \times 15

\qquad \sf  \dashrightarrow \: 300 \:  \: cm {}^{2}

2. Area of first triangle :

\qquad \sf  \dashrightarrow \:  \cfrac{1}{2} \times  (base) \times (height)

\qquad \sf  \dashrightarrow \:  \cfrac{1}{2} \times  (20 - 18) \times (15)

\qquad \sf  \dashrightarrow \:  \cfrac{1}{2} \times  (2) \times (15)

\qquad \sf  \dashrightarrow \: 15 \:  \:  cm {}^{2}

3. Area of second triangle :

\qquad \sf  \dashrightarrow \:  \cfrac{1}{2} \times  (base) \times (height)

\qquad \sf  \dashrightarrow \:  \cfrac{1}{2} \times  (6) \times(20)

\qquad \sf  \dashrightarrow \: 3 \times 20

\qquad \sf  \dashrightarrow \: 60 \:  \: cm {}^{2}

Area of shaded region is :

\qquad \sf  \dashrightarrow \: 300 - (15 + 60)

\qquad \sf  \dashrightarrow \: 300 - 75

\qquad \sf  \dashrightarrow \: 225 \:  \: cm {}^{2}

A parabola can be drawn given a focus of
Volgvan

Answer:

y=-\frac{1}{4}(x-2)^{2}+9

Step-by-step explanation:

Any point on a given parabola is equidistant from focus and directrix.

Given:

Focus of the parabola is at (2,8).

Directrix of the parabola is y=10.

Let (x,y) be any point on the parabola. Then, from the definition of a parabola,

Distance of (x,y) from focus = Distance of (x,y) from directrix.

Therefore,

\sqrt{(x-2)^{2}+(y-8)^{2}}=|y-10|

Squaring both sides, we get

(x-2)^{2}+(y-8)^{2}=(y-10)^{2}\\(x-2)^{2}=(y-10)^{2}-(y-8)^{2}\\(x-2)^{2}=(y-10+y-8)(y-10-(y-8))...............[\because a^{2}-b^{2}=(a+b)(a-b)]\\(x-2)^{2}=(2y-18)(y-10-y+8)\\(x-2)^{2}=2(y-9)(-2)\\(x-2)^{2}=-4(y-9)\\y-9=-\frac{1}{4}(x-2)^{2}\\y=-\frac{1}{4}(x-2)^{2}+9

Hence, the equation of the parabola is y=-\frac{1}{4}(x-2)^{2}+9.
