To find the area of the first figure, which is a rectangle, we can use the formula: Area = length x breadth.

Given that the length is 5 and the breadth is 6, the area of the first figure is: 5 x 6 = 30 square units.

To find the area of the second figure, which is a triangle, we can use the formula: Area = 0.5 x base x height.

Given that the base is 3 and the height is 4, the area of the second figure is: 0.5 x 3 x 4 = 6 square units.

Since the two figures are joined together, the total area of the figure is the sum of the areas of the rectangle and the triangle: 30 + 6 = 36 square units.
