Answer:
If use the area of the frame the area of the photo will be included
Area of frame = (22 + 2 x) * (20 + 2 x) = A
440 + 2 x ( 20 + 22) + 4 x^2 = A
A = 4 x^2 + 84 X + 440

is already in simplest form because 23 is a prime number, which means that it is only divisible by 1 and itself (23). Hope this helps! :)
Since PQ=PR
=> Q is the midpoint of PR
Hope this helps you
