Answer:
Option A is correct
11 inches by 11 inches
Step-by-step explanation:
Area of square (A) is given by:
\(A = \text{Side} \times \text{Side}\)
As per the statement:
Miriam reduced a square photo by cutting 3 inches away from the length and the width so it will fit in her photo album.
The area of the reduced photo is 64 square inches.
Given the equation:
\((x-3)^2 = 64\) where, x is the the side measure of the original photo.
Solve for x;
Take square root both sides we have;
\(x-3 = \sqrt{64}\)
⇒\(x-3 = 8\)
Add 3 to both sides we have;
x-3+3 = 8+3
⇒x = 11 inches
Therefore, the dimensions of the original photo were : 11 inches by 11 inches
