In the given figure, there is a rectangle and two semicircles.
Length of the rectangle(l) = 2m
Breadth of the rectangle(b) = 1.4m
Area of a rectangle = l × b
                            = 2 × 1.4 = 2.8 m²

There are two semicircles of equal diameter and hence, we can consider them as a single circle.
Diameter of the circle = 1.4m ⇒ radius, r = 0.7 m
Area of a circle = πr²   
                       = (22/7) × (0.7)² (Consider the value of π as 22/7)
                       = 1.54 m²

Total area of the figure = Area of the rectangle + Area of the circle
                                 = 2.8 + 1.54
                                 = 4.34 m²
