1. The fence around the playground costs 90 dollars per 17-yard roll. Laying the grass across the area costs 400 dollars per 55 square yards. How much did the
fencing and grass for this playground cost to build?
2. There's a new playground going up in nearby Burnham park. Burnham has a
budget about 3 times greater than Springfield's, and wonders if they can build
their playground by scaling up Springfield's playground dimensions by 3.
Calculate the cost of grass and fencing for a playground that has been dilated
using a scale factor of 3. Will Burnham's budget cover the costs?
3. How many children could play on the playground that is scaled up by a scale
factor of 3, at the same density of kids per square yard as on Springfield's
playground? Hint: density is the total number of kids over the area in square
yards.
4. Recommend a playground shape and size that would fit Burnham's budget and
hold at least 3 times as many kids as Springfield's playground. How many kids
can your playground hold?
