base = 3*3 = 9 sq. in.
side = 1/2 *3*6 = 9 sq. in.
4 sides x 9 = 36 + 9 (base) = 45 in^2
Answer is A
(x^2+2x+1)+(y^2+6y+9)=10
(x+1)^2 + (y+3)^2 = 10
centre (-1,-3) radius sqrt10
Ti find this you need to multiply 36 and 1/4. You should get 9. I hope this is what you meant!

To express the equation in a point-slope form, obtain first the slope of the line between the points. The slope, m, of this line is,
(y2 - y1)/(x2 - x1) = (8 - 0)/(2--2) = 2
The point-slope form of the line is generally expressed as
y - y2 = m (x - x2)
Thus, in this given the point-slope form is,
y - 8 = 2 (x - 2)
