Question

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?

Answer 1

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
