The length and breadth of a rectangle are extended by 2 units each. The sides of the original figure were 1 unit and 7units respectively.
From the above, we can conclude that area of the new figure will be 27
Find the area of all the shapes in the new figure using area= length×width
We get the areas as 14,4,7 and 2
Area of new figure=14+4+7+2=27
