Final answer:
The remaining area in the rectangle after removing a square can be found by subtracting the area of the square from the original area.
Step-by-step explanation:
The area of the rectangle can be found by multiplying the length by the width. The original rectangle has a length of 8 feet and a width of 4 feet, so the area is 8 * 4 = 32 square feet. After removing a 2' square from one corner, the remaining area can be calculated by subtracting the area of the square (2 * 2 = 4 square feet) from the original area: 32 - 4 = 28 square feet. Therefore, 28 square feet would remain in the rectangle.
