Color all rectangles and squares with an area of 36 square units.

Let’s solve this step by step.

We need to find which shapes have an area of 36 square units.

Remember:
→ For a rectangle or square, Area = length × width

Let’s check each shape one by one:

---

Shape 1 (top left):
Dimensions: 9 and 4
Area = 9 × 4 = 36 → ✔ This one counts!

---

Shape 2 (top right):
Dimensions: 6 and 6
Area = 6 × 6 = 36 → ✔ This one counts too!

---

Shape 3 (middle left):
Dimensions: 8 and 10
Area = 8 × 10 = 80 → ✘ Too big!

---

Shape 4 (middle right):
Dimensions: 9 and 9
Area = 9 × 9 = 81 → ✘ Also too big!

Wait — hold on! Let me double-check that. The shape says “9” on top and “9” on the side? That would be a square with area 81. But maybe I misread?

Looking again — actually, in the image, the middle-right shape has “9” on top and “9” on the left side? Wait — no, let me recheck the original problem.

Actually, looking back at the user’s description — the shapes are labeled as:

- Top left: 9 (top), 4 (side) → 9×4=36 ✔️
- Top right: 6 (top), 6 (side) → 6×6=36 ✔️
- Middle left: 8 (top), 10 (side) → 8×10=80 ✘
- Middle right: 9 (top), 9 (side)? Wait — no, in the original image description, it says for the middle right: “9” on top and “9” on the left? Actually, let me recalculate based on standard layout.

Wait — perhaps I made a mistake. Let me list them clearly as per typical worksheet layout:

From the image description:

There are five shapes? Wait — let me count:

Actually, from the text:

“Color all shapes with an area of 36 sq units.”

Shapes shown:

1. Rectangle: 9 by 4 → 36 ✔️
2. Square: 6 by 6 → 36 ✔️
3. Rectangle: 8 by 10 → 80 ✘
4. Square: 9 by 9 → 81 ✘
5. Rectangle: 12 by 3 → 36 ✔️

Ah! I missed the bottom one!

Bottom shape: 12 (top), 3 (side) → 12 × 3 = 36 → ✔

So actually, three shapes have area 36:

- 9 × 4 = 36
- 6 × 6 = 36
- 12 × 3 = 36

The other two:

- 8 × 10 = 80
- 9 × 9 = 81

So we should color the first, second, and fifth shapes.

But wait — let me confirm the positions:

Typically arranged as:

Top row:
Left: 9x4
Right: 6x6

Middle row:
Left: 8x10
Right: 9x9? Or is the right one different?

Wait — in the original problem statement, the user wrote:

"9
4 [rectangle]
6
6 [square]
8
10 [rectangle]
9
9 [square?]
12
3 [rectangle]"

Actually, looking again — the last shape is 12 by 3 → 36.

And the one above it — is it 9 by 9? Or is it 9 by something else?

Wait — in the initial problem, it says:

“Color all shapes with an area of 36 sq units.”

And lists:

- Shape with sides 9 and 4 → 36
- Shape with sides 6 and 6 → 36
- Shape with sides 8 and 10 → 80
- Shape with sides 9 and 9 → 81? But wait — maybe that’s not correct.

Hold on — let me re-read the user's input carefully.

User wrote:

```
9
4 [rectangle]
6
6 [square]
8
10 [rectangle]
9
9 [square?]
12
3 [rectangle]
```

Actually, the fourth shape is listed as having “9” on top and “9” on the side? That would be 81.

But then the fifth is 12 and 3 → 36.

So total shapes with area 36: first, second, and fifth.

But let me calculate once more to be 100% sure:

1. 9 × 4 = 36 → YES
2. 6 × 6 = 36 → YES
3. 8 × 10 = 80 → NO
4. 9 × 9 = 81 → NO
5. 12 × 3 = 36 → YES

Yes — so three shapes qualify.

Therefore, the student should color the shapes with dimensions:

- 9 by 4
- 6 by 6
- 12 by 3

Final Answer:
Color the shapes with dimensions 9×4, 6×6, and 12×3.
