Ineed with this problem if someone would me out. you !

At 5 hours the get $60 then at 3 hours they get $50 therefore they are paid $5 per hour

I believe you just need to calculate the slope. 

get two points from the graph, i will pick (0,35) and (5,60)

now find slope =5 

(60-35)/(5-0)= 25/5 = $5 per hour

hope that helps and if right? 

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
