Answer:
If I did the math correctly, then the answer is 11.
Step-by-step explanation: 1 40 foot long piece and 2 24 ft. long pieces.
24 times 2 is 48 plus 40 is 88.
The width of her house, based on the question, is also 40 ft. so you could add 40 onto it, but I actually believe the answer is 11, because it's 88 feet. The fence piece is 8 ft. long, so divide 88 by 8 and you get 11.
