Question

Joel wants to fence off a triangular portion of his yard for his chickens. The three pieces of fencing he has measure 8 feet, 15 feet, and 20 feet long. Use this information to answer 8-9

8. Joel cut the longest piece of fencing in order to make a right triangle. Find the perimeter of Joel’s fence.

9. If it takes Joel 30 seconds to
foot of fencing, how many total minutes will it take him to install the fence?


Please help me thank you so much.

Answer 1

8. Joel will not form a right triangle.

9.20 minutes

Explanation:

8. First use theorem

Right triangle theorem

c²=a²+b²

c=20 ft

a=8ft

b=15 ft

20² =8²+15²

simplify

400= 64+225

400 does not = 289

9.

Part B)

if Joel cut the longest piece of fencing in order to make a right triangle

longest part is 17^2

a²+b²=289

c²=√289

c=17 ft

the perimeter of the fence is

a+b+c

17+8+15

perimeter is

40 ft

30 sec to install 40 ft(perimeter)

x=40*30

x=1200 seconds

x=1200/60 in minutes

x=20 minutes
