Let’s go step by step to figure out which pictures show
rectangular arrays.
Remember:
A
rectangular array means objects are arranged in
equal rows and equal columns, forming a rectangle — like a grid. No gaps, no circles, no weird shapes — just straight rows and columns that line up perfectly.

Look at each picture one by one:
1.
Stars in a circle → Not rows or columns. It’s a circle.
✘ Not a rectangular array.
2.
Houses (2 rows of 4) → Top row: 4 houses. Bottom row: 4 houses. All lined up.
✔ This is a rectangular array.
3.
Smiley faces in a pyramid shape → Rows have different numbers: 4, then 2, then 3, then 5. Not equal rows or columns.
✘ Not a rectangular array.
4.
Snails (3 rows of 3) → Each row has 3 snails. 3 rows total. Perfect square (which is also a rectangle).
✔ Rectangular array.
5.
Triangles in a hollow square → The middle is empty. Not filled in. Arrays must be solid rectangles with no holes.
✘ Not a rectangular array.
6.
Beach balls (4 rows of 5) → Every row has 5 balls. 4 rows total. All lined up.
✔ Rectangular array.

So the correct ones are:
- Houses
- Snails
- Beach balls
Final Answer:
Check the boxes under the houses, the snails, and the beach balls.
