Answer:
A≈86.93m²
Step-by-step explanation:
If it can be assumed that the total number paper and bags is the same for both orders, then:
#bags ordered in the spring=7*(150/3)=350, so the total of both is 150+350=500. A 5:5 ratio means that the wrapping paper and bags were bout in equal quantities. That means 500/2=250 for each.
The simplest ratio is 1/3. Equivalent ratios would be 3/9 and 5/15.
Area=pi x radius squared so (3.14)(10)squared = 314
