Solution

## The correct option is B 198 sq.mThe lawn as given in the diagram is: It can be divided into two rectangles as follows: So, total area of the lawn will be: ⇒ Area of blue rectangle + Area of red rectangle Now, the area of a rectangle can be calculated as: Area=Length×Breadth. So, area of the blue rectangle is: =12m×14m=168 sq.m And, area of red rectangle is: =6m×5m=30 sq.m ∴ Total area of the lawn will be ⇒ Area of blue rectangle + Area of red rectangle ⇒168 sq.m+30 sq.m=198 sq.m So, the lawn's total area is 198 sq.m.
