Area of a rectangle is calculated using which formula?

Area of a rectangle is calculated using which formula?

• A. Area = length x width
• B. Area = width x height
• C. Area = length + width
• D. Area = 2(length x width)

Answer: (A)

Area measures how much space is inside a rectangle, so you find it by multiplying the two dimensions that describe its size in each direction. Multiplying length by width counts how many unit squares fit across the length and along the width, giving the total area. The other options don’t describe interior space correctly: adding the sides isn’t area, doubling the product gives twice as much space, and using height instead of length is just a naming difference, not the correct way to measure the rectangle’s interior with the given dimensions. So, area equals length times width.
