Let's solve the problem step by step.
---
Task:
Shade all the rectangles below.
Then,
count how many rectangles there are.
---
Step 1: Understand what a rectangle is
A
rectangle is a four-sided shape (quadrilateral) with:
- Opposite sides equal and parallel
- Four right angles (90°)
- Two pairs of equal sides
Note: A square is a special type of rectangle (all sides equal, but still has 4 right angles), so squares
are rectangles.

Step 2: Identify all rectangles in the image
Let’s go through each shape one by one:
1.
Top row (left to right):
- Triangle →
✘ not a rectangle
- Right triangle →
✘ not a rectangle (only 1 right angle)
-
Rectangle →
✔ yes
- Triangle →
✘
2.
Second row:
- Circle →
✘
-
Large rectangle →
✔
-
Vertical rectangle →
✔
- Pentagon →
✘
3.
Third row:
- Small triangle →
✘
- Trapezoid →
✘ (not all angles are right, sides not equal/parallel as required)
-
Small square →
✔ (a square is a rectangle)
-
Small horizontal rectangle →
✔
4.
Fourth row:
-
Horizontal rectangle →
✔
- Circle →
✘
- Triangle →
✘
- Large triangle →
✘
---
Now, list all the rectangles:
Let’s count them carefully:
1. Top center-right small rectangle
✔
2. Middle-left large rectangle
✔
3. Middle-center vertical rectangle
✔
4. Middle-right small square
✔
5. Middle-bottom small horizontal rectangle
✔
6. Bottom-left horizontal rectangle
✔
Wait — let’s double-check positions:
Looking at the layout:
-
Row 1: One rectangle (middle-right)
-
Row 2: Two rectangles (large horizontal, vertical)
-
Row 3: Two rectangles (small square, small horizontal)
-
Row 4: One rectangle (bottom-left)
That’s
6 rectangles.
But wait — let’s check again.
Let me number the shapes for clarity:
1. △ (top left) – no
2. △ (right triangle) – no
3. ▭ (small rectangle) –
yes
4. △ (top right) – no
5. ○ (circle) – no
6. ▭ (large rectangle) –
yes
7. ○ (small circle) – no
8. ▭ (vertical rectangle) –
yes
9. Pentagon – no
10. △ (small triangle) – no
11. Trapezoid – no
12. ▭ (small square) –
yes
13. ▭ (small horizontal rectangle) –
yes
14. ▭ (bottom-left rectangle) –
yes
15. ○ (circle) – no
16. △ (triangle) – no
17. △ (large triangle) – no
So the rectangles are:
- #3 – small rectangle
- #6 – large rectangle
- #8 – vertical rectangle
- #12 – small square
- #13 – small horizontal rectangle
- #14 – bottom-left rectangle
✔ That’s
6 rectangles.

Answer:
You should
shade these 6 shapes, and then write:
>
How many rectangles can you count?
>
6
