Explanation:

Step1: Estimate canoe length

A typical canoe is ~3 yards long, so 3 yardsticks = 3 yards.

Step2: Estimate pool length

A small residential pool is ~30 yards long, so 30 yardsticks = 30 yards.

Step3: Calculate garden length

Add Mr. and Mrs. Agarwal's yardsticks: $4 + 4 = 8$

Step4: Explain picnic table estimation

A picnic table is ~2 yards. Use a yardstick: place end-to-end twice to match its length, so 2 yardsticks = 2 yards.

Answer:

1. Estimate: 3 yardsticks, or 3 yards
2. Estimate: 30 yardsticks, or 30 yards
3. about 8 yards
4. Example: A standard park bench is about the same length as a picnic table. To estimate, place a yardstick end-to-end along the bench: it will fit about 2 times, so the length is about 2 yards.
