Final answer:
The area of the square is 36a^2 - 52a + 676 square inches.
Step-by-step explanation:
To find the area of a square, we need to square the length of one of its sides. In this case, the side length is given as 6a - 26 inches. To find the area, we square this expression:
Area = (6a - 26)^2 = 36a^2 - 52a + 676 square inches
So, the area of the square is 36a^2 - 52a + 676 square inches.
