No, a 7x11 inch rectangular baking pan is not the same as a 9x9 inch square pan. They have different dimensions and, therefore, different areas.
A 7x11 inch rectangular baking pan has an area of 77 square inches (7 inches wide x 11 inches long = 77 square inches).
A 9x9 inch square pan, on the other hand, has an area of 81 square inches (9 inches wide x 9 inches long = 81 square inches).
So, the 9x9 inch square pan is slightly larger in terms of area compared to the 7x11 inch rectangular pan. When choosing a baking pan, it's essential to consider the dimensions and the desired outcome of your recipe. Depending on the recipe and its required volume, the difference in size could affect baking times and the thickness of the final baked product.
