Question 103834: The city is planning to build a small playground on arectangle section of a park. The perimeter of the playground is 80 feet. The two longer sides of the playground will each be 25 feet.
Now what I did was this..
80/5= 16 25/5 & 25/5=5+5=10*16=160/5=32ft square.
But I have a feeling is wrong like I'm missing something I used the L*W operation
also..
A rectangle yard is surrounded by a fence that is 26 feet long. The area of the yard is 36 ft square. Determine the dimension of the yard.
I did this...
26/2 & 36/2 which gave me
13 * 18 = 234/2= 117 square feet
again I used the L*W operation still I feel is wrong

Question 103797: If there is a goat tied to a rectangular barn on a 50 foot lead and the barn is 20 feet by 20 feet (floor), what is the maximum grazing area? If there are regions you can't find the area of, provide as good an estimate as you can. Assume the goat is tied to a corner outside the barn, cannot get in, and that the barn is not grazing area. (Remember, this will be based on parts of circles, no other shapes...the goat's rope will only get shorter when he tries to go around the barn...)
7. When the rope goes around the barn, what is the new radius? How much of a circle can it make without hitting the barn or overlapping area you've already found? What is that area?
8. When the rope goes around the barn the other way, what is the new radius? How much of a circle can it make without hitting the barn or overlapping area you've already found? What is that area?
9. The areas you found in 7 and 8 overlap each other. How much do they overlap? What *approximate* shape do they make? What is that area?
10. What is the total grazing area the goat can reach?
