Finding the area of a rectangle is an important ability that allows you to do things from completing geometry homework to planning home improvement projects. The area of a rectangle is the amount of space that a rectangle covers. You can find the area of a rectangle using a simple algebraic expression in which "L" x "W" = "X," with X as your variable, or answer.

Measure the length of your rectangle. Use this measurement as L.

Measure the width of your rectangle. This measurement is W.

Set up your algebraic expression: L times W = X, or the area.

Solve your equation by multiplying L times W to find the area.

#### Tip

Use a calculator as necessary.
