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.
Things You'll Need
 Ruler or tape measure

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.
Tips & Warnings
