What is the area if the composite figure in square units if the numbers are 5, 2, 3, and 4?

To find the area of the composite figure, we first need to break it down into two separate shapes: a rectangle and a triangle.

The rectangle has a length of 5 units and a width of 2 units, so its area is:
Area of rectangle = length x width = 5 x 2 = 10 square units

The triangle has a base of 3 units and a height of 4 units, so its area is:
Area of triangle = 0.5 x base x height = 0.5 x 3 x 4 = 6 square units

Now, we add the areas of the rectangle and triangle to find the total area of the composite figure:
Total area = area of rectangle + area of triangle
Total area = 10 + 6 = 16 square units

Therefore, the area of the composite figure is 16 square units.
