To find the area of a rectangular garden plot, you use the formula for the area of a rectangle:
Area = Length × Width
In this problem, the length of the garden plot is 11 meters and the width is 16 meters. Let's substitute these values into the formula:
Area = 11 meters × 16 meters
Area = 176 square meters
So, the area of Mang Mario's rectangular garden plot is 176 square meters. This means that the total space within the perimeter of the garden plot is 176 square meters.
