What is the formula of area of rectangle?

As a math teacher, I always tell my students to remember that area is measured in square units (like cm², m², ft²). The formula works because you're essentially counting how many unit squares fit inside the rectangle. It's different from perimeter, which is the distance around the shape. This is fundamental geometry that you'll use throughout life - whether you're planning a garden layout or calculating material quantities for DIY projects.

For a rectangle, the area is calculated with the formula: Area = Length × Width. It’s pretty straightforward, but don’t forget both measurements should be in the same unit. For example, if your length is 8 cm and width is 4 cm, then area = 8 × 4 = 32 cm².

Hey! The formula for the area of a rectangle is super simple: Area = Length × Width. Sometimes written as A = l × w. You just multiply the length of the rectangle by its width. For example, if a rectangle is 5 meters long and 3 meters wide, the area would be 5 × 3 = 15 square meters. This is one of those basic math formulas that comes in handy more often than you'd think - from measuring rooms for carpet to figuring out how much paint you need for a wall!

Think of it this way: a rectangle is basically just rows of equal squares stacked side by side. If you know how long it is (length) and how wide it is (breadth), multiply the two. That’s why the formula is Length × Breadth. I always visualize it as filling tiles on the floor, helps me remember.
