(x+2)^2 + (y+7)^2 =1296

Step-by-step explanation:

The equation of a circle is given by

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center of the circle and r is the radius

(x- -2)^2+ (y- -7)^2 =  36^2

(x+2)^2 + (y+7)^2 =1296

hi,

the area of abcd is 245.

3*24=230

4*94=1039

2*12=24

add all of them up, you get 2450
