This is distance formula is sqr. root of (x1-x2)^2 + (y1-y2)^2 
(3-(-4))^2+ (-94-(-195))
 7^2                101^2
  49+                10,201
square root of 10250

PLEASE HELP! Urgent!!!

Answer:

\frac{9}{2}\pi +35

Step-by-step explanation:

The area of trapezoid is given by the formula:

A=\frac{1}{2}(b_1+b_2)h

Where

A is the area

b_1 is base 1

b_2 is base 2, and

h is the height

Looking at the figure, base 1 is the left line which goes from y = 3 to y = 3, so 6 units. Also, base 2 is the right line which goes from y = -3 to y =5, so 8 units.

The height is the horizontal distance in the middle, which goes from x = -2 to x = 3, so 5 units. Hence area of trapezoid is:

A=\frac{1}{2}(b_1+b_2)h\\A=\frac{1}{2}(6+8)*5\\A=35

Now, area of semicircle is:

A=\frac{\pi r^2}{2}

Where

A is the area

r is the radius

Looking at the figure, the diameter (twice radius) goes from y = -3 to y = 3, so 6 units. But radius is half of that, so 3 units. Hence area of semicircle is:

A=\frac{\pi r^2}{2}\\A=\frac{\pi (3)^2}{2}\\A=\frac{9}{2} \pi

Total area of the figure is \frac{9}{2}\pi +35
