a. Construct a rectangle with 3 rows of 2 tiles.

Answer:

3 rows of 2 tiles.

Explanation:

Here, we have constructed a rectangle with 3 rows of 2 tiles and the addition equation will be 2 +2 + 2 which is 6.

b. Construct a rectangle with 3 columns of 2 tiles.

Answer:

3 columns of 2 tiles.

Explanation:

Here, we have constructed a rectangle with 3 columns of 2 tiles and the addition equation will be 3 + 3 which is 6.

Question 3.

a. Construct a rectangle using 10 tiles.

Answer:

2 rows of 5 tiles.

Explanation:

Here, we have constructed a rectangle with 2 rows of 5 tiles and the addition equation will be 5 + 5 which is 10 tiles.

b. Construct a rectangle using 12 tiles.

Answer:

2 rows of 6 tiles.

Explanation:

Here, we have constructed a rectangle with 2 rows of 6 tiles and the addition equation will be 6 + 6 which is 12.

Question 4.

a. What shape is the array pictured below?

Answer:

The shape of the above figure is a rectangle.

Explanation:

The shape of the above array which is pictured is a rectangle, as rectangle has 4 sides and 4 corners and its two sides meet at right angles. And in the rectangle we can see that opposite sides have same length and parallel to each other.

b. In the space below, redraw the above shape with one more column.

Answer:

3 columns of 4.

Explanation:

As in the above image, we can see that there are three columns of 4, and we have to redraw the above image by adding one column. So there will be four columns of 4.

c. What shape is the array now?

Answer:

The shape of the array is square.

Explanation:

The shape of the array is square, as all sides of the shape are equal.

d. Draw a different array of tiles that is the same shape as 4(c).

Answer:

3 columns of 3.

Explanation:

As in the above image, we can see that there are four columns of 4 which is square and we have to redraw with different array of the tiles, so here we will construct 3 columns of 3.
