Rhiannon has a rectangular bedspread that measures 234 in. by 245 in. she wants to sew a fringe around the edge of the bedspread. whag length of fringe does rhiannon need to purchase. rihannon gets a new bedspread that is 33 in longer. what length of the fringe does rhiannon need for the longer bedspread?

We know that
perimeter of a rectangular shape=2*[length +wide]
in this problem
length=245 in
wide=234 in
so
perimeter=2*[245+234]> 958 in

the answer Part a) is
Rhiannon needs to purchase 958 in of fringe 

Part b) Rihannon gets a new bedspread that is 33 in longer. What length of the fringe does rhiannon need for the longer bedspread?

the new perimeter=original perimeter+2*33> 958+66> 1024 in

the answer Part b) is 
Rhiannon needs 1024 in for the longer bedspread

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
