A rectangular plot has one side measuring 4 meters and the diagonal length is 5 meters. What is the total area of this plot?

Explanation

Given one side of the rectangle as 4 m and the diagonal as 5 m, we apply the Pythagorean theorem to find the other side: √(5² - 4²) = √(25 -16) = 3 m. The area is then 4 m × 3 m = 12 square meters.
