Ah...summer is here! That makes me think of a math problem.

Moe helps out the seniors Larry and Curly on his block by mowing their lawns during the summer. He can mow a square lawn of side length 30 m in 45 minutes.

a) If he works at the same rate, how many minutes will it take Moe to mow a square lawn of side length 60 m?

b) What are the dimensions of possible rectangular lawns with the same area as the lawn of side 30 m, and dimensions which are whole numbers? Which of these are you likely to see in the city?

If you write me, I'll write back. Even in the summer.

Joe/Mr. Reid
