Problem of the Week
Problem A
Making Plans
Mr. Lee’s Grade 4 class is going to create a play area for their school’s daycare that includes a picnic table and a sandbox. They want square foam tiles under the entire play area (even under the sandbox and under the picnic table). There will be a rubber trim surrounding the play area to keep the tiles in place.
This is a picture of their plan. Each small square represents one square foam tile.
How many foam tiles do the students need to complete this job?
If each foam tile is \(0.5\) m by \(0.5\) m, how many metres of rubber trim is needed to surround the entire play area?
