Let’s solve each problem one by one. We’ll use estimation — that means we don’t need exact answers, just good guesses based on the numbers given.
---
1. Flower Petals:
One sunflower has about 100 petals.
There are 50 sunflowers.
So, total petals = 100 × 50 =
5,000 petals
---
2. Tree Height:
One maple tree is 50 feet tall.
We have 10 trees in a row.
But height doesn’t add up when trees are side by side — they’re not stacked!
So, the height of the *row* is still just the height of one tree:
50 feet
*(Note: If the question meant “total height if stacked,” it would be 500 feet — but that’s not realistic for a row of trees. So we assume it’s asking for how tall the row appears, which is same as one tree.)*
Wait — let’s read again: “Estimate the height of a row of 10 maple trees.”
In real life, a row of trees doesn’t get taller — it gets longer. But since it says “height,” maybe it’s a trick? Or maybe it means if you lined them up vertically? That doesn’t make sense.
Actually, in math problems like this, sometimes “row” just means group — and they want total height if added. Let’s check context.
Looking at other problems — #3 is seed count (multiplication), #4 is area (multiplication). So likely, #2 wants multiplication too.
So: 50 feet per tree × 10 trees =
500 feet
I think that’s what they expect. Even though it’s not realistic, for estimation practice, we multiply.
→
500 feet

3. Seed Count:
One packet = 50 seeds
25 packets → 50 × 25
Let’s calculate: 50 × 25 = 50 × (20 + 5) = 1000 + 250 =
1,250 seeds
---
4. Garden Area:
Square garden bed, 10 feet on each side → area of one = 10 × 10 = 100 sq ft
5 such beds → 100 × 5 =
500 square feet
---
5. Leaf Collection:
20 leaves per day
7 days in a week → 20 × 7 =
140 leaves
---
6. Plant Growth:
Grows 1 inch per day
2 weeks = 14 days → 1 × 14 =
14 inches
---
7. Garden Harvest:
Each plant produces 100 strawberries
10 plants → 100 × 10 =
1,000 strawberries
---
8. Photosynthesis Time:
6 hours per day
Month ≈ 30 days → 6 × 30 =
180 hours
---
9. Flowering Season:
Blooms for 4 weeks
1 week = 7 days → 4 × 7 =
28 days
---
10. Plant Reproduction:
One fruit has 50 seeds
8 fruits → 50 × 8 =
400 seeds
---
Now, let’s double-check all calculations:
1. 100 × 50 = 5,000
✔
2. 50 × 10 = 500
✔ (assuming they mean total height if combined)
3. 50 × 25 = 1,250
✔
4. 10×10=100; 100×5=500
✔
5. 20×7=140
✔
6. 1×14=14
✔
7. 100×10=1,000
✔
8. 6×30=180
✔
9. 4×7=28
✔
10. 50×8=400
✔
All correct!
Final Answer:
1. 5,000
2. 500
3. 1,250
4. 500
5. 140
6. 14
7. 1,000
8. 180
9. 28
10. 400
