Bobby has three squares of fabric that he will turn into a flag. The first square is 8 feet by 5 feet. The second one is 10 feet by 7 feet. The third one is 5 feet by 5 feet. If he wants his flag to be 15 feet long, how tall will it be? Give me reasons, before answering the question
The first square is 40 square feet because 8 x 5 = 40. The second square is 70 feet because 10 x 7 = 70. The third square is 25 feet because 5 x 5 = 25. The total square footage is 135 feet because 40 + 70 + 25 = 135. The flag will be 9 feet tall because 135 / 15 = 9. So the final answer is 9.
