4+4+4+4+4+4=24yd is the perimeter.
Step-by-step explanation:
1 hour 50 minutes = 110 mins
1 1/2 hours = 90 mins
add all these:
110
90
85
55
35
when you add all these you get 375
every hour has 60 minutes
375 ÷ 60 = 6.15
if he starts at 9 am and he cleans for 6.15 hours he will be finished by 3:15pm.
The vertex would be at (5,-2)
I believe the answer is $45.75.
I hope this helps.
