Answer:
1346cm
Step-by-step explanation:
First of all it is fringe, not french or friends.
Now, as we know that perimeter'P' of a rectangular is given by
P=2(length +width)
Given
length=435 cm
width=238 cm
P=2(435 +238) => 1346cm
Therefore, Rhiannon needs to purchase 1346cm of fringe
9.95(0.75)(1.06)=7.91
The .75 is the coupon and 1.06 is the sales tax.
