Identify the formula for area of a rectangle
Substitute the given values
Multiply length by width
Final answer
A = length × width
This formula calculates the area of a rectangle.
A room measuring 40 meters by 10 meters has a floor area of 400.0 square meters
A rectangular field 40 feet long and 10 feet wide covers 400.0 square feet
A 40m × 10m rectangular pool has a surface area of 400.0 m²
The area of a rectangle is a fundamental concept in geometry. Area measures the amount of space inside a 2D shape, typically expressed in square units.
By using the formula A = length × width, we can quickly and accurately calculate the area for any rectangle when we know the required measurements.
