Question

hamlin is using carpet squares to make a rectangular shape. the dimensions of the rectangle are 4 units by 7 units. which expression can you use to find the total number of carpet squares hamlin needs to make the shape? 4 + 4 + 4 + 4 + 4 + 4 + 4 7 + 7 + 7 4 + 7 + 4 + 7 4 + 7

Explanation:

Step1: Understand the problem

We need to find the total number of carpet squares. The rectangle has dimensions 4 units by 7 units. This means there are 7 rows and 4 columns.

Step2: Relate to addition

If we consider the number of squares in each row (4) and there are 7 rows, then the total number of squares is \(4 + 4+4 + 4+4 + 4+4\) (since we are adding the number of squares in each of the 7 rows).

Answer:

\(4 + 4+4 + 4+4 + 4+4\)
