Answer: 5,000 square feet
Step-by-step explanation:
50 feet multiplying by 100 feet equal to 5,000 sq ft.
The word "by" means to multiply.
Looking for square feet means to find the area.
Also, 100 feet by 50 feet tells me that we are talking about a rectangle whose length is 100 feet and width is 50 feet.
A = length times width
A = (100 feet)(50 feet)
A = 5,000 square feet
