Area of rectangle 15 by 4

Step by step

The question

Question: find the area of a rectangle 15 long and 4 wide.

1 What area means

Area is how much space is inside.

We count the 1 by 1 squares that fit.

One row has 15 squares.

There are 4 rows.

2 Length times width

So the area is length times width: A = length × width.

Squares in a row, times the rows.

Now put the numbers in: length = 15 and width = 4.

15 times 4 is 60.

So the area is 60 square units.

Let's look back.

First: what area means.

Last: length times width.
