# Area of rectangles review

Review the basics of area of rectangles and try some practice problems.

## What is area?

Area is the space inside of a two-dimensional shape. We can also think of area as the amount of space a shape covers.
For example, the rectangle below has an area of 12 square units because it covers 12 square units.

## Area of a rectangle formula

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.
A, r, e, a, space, o, f, space, r, e, c, t, a, n, g, l, e, equals, l, e, n, g, t, h, times, w, i, d, t, h

### Example 1:

A, r, e, a, equals, l, e, n, g, t, h, times, w, i, d, t, h
empty space, equals, 6, times, 2
empty space, equals, 12, space, s, q, u, a, r, e, space, u, n, i, t, s

### Example 2:

A, r, e, a, equals, l, e, n, g, t, h, times, w, i, d, t, h
empty space, equals, 7, times, 4
empty space, equals, 28, space, s, q, u, a, r, e, space, u, n, i, t, s
