We can count the squares to find our answer. The correct answer is is 

In order to solve this problem using multiplication, we must multiply the multiplier by each digit of the multiplicand to get the answer, which is called the product.

For this problem,  is the multiplier and  is the multiplicand. 

First, we multiply  and 

Because the product is greater than , we carry the  and add it to the next product. 

Next, we multiply  and  and then add the  we carried.

Example Question #3781 : Numbers And Operations

Solve  by making a rectangular array. 

Possible Answers:

Correct answer:

Explanation:

Using our problem to make a rectangular array, we know that we are going to use a total of  squares, and one dimension of the rectangular array is going to have  squares, we'll make that the width. Our answer will be how many squares high the rectangle array is, or the height. 

We can start with  squares and keep adding  on top of the previous  until we've used all  squares. Our rectangular array is  squares high.
