Answer:
A. 11 inches by 11 inches
Step-by-step explanation:
Here, the given equation,
![(x-3)^2=64](https://tex.z-dn.net/?f=%28x-3%29%5E2%3D64)
Where x represents the side of the original photo,
![x-3=\pm 8](https://tex.z-dn.net/?f=x-3%3D%5Cpm%208)
If x - 3 = 8 ⇒ x = 11.
If x - 3 = -8 ⇒ x = -5,
Since, the side can not be negative,
Thus, the side of the original figure is 11 inches,
Also, the photo is square shaped ( quadrilateral having equal sides ),
Hence, the dimension of the original photo is,
11 inches × 11 inches,
= 11 inches by 11 inches.
Option A is correct.
