5. Ans: Option (D)
Explanation:
First let's find the total area of the yard:
Total Area of the Yard = 14x * 19x =
Now the area of the circular fountain:
Area of the Circular Fountain =
Since, r=6x
Therefore,
Area of the Circular Fountain =
Now the final Area of the yard would be:
Final area of the Yard = Total Area of the Yard - Area of the Circular Fountain
Final area of the Yard = - 
=> Final area of the Yard =
(Option D)
6. Ans: Option (A)
Explanation:
First let's find the total area of the lot:
Total Area of the lot= 6x * 10x =
Now the area of the stadium:
Area of the stadium = 1x * 4x =
Now the final Area of the lot would be:
Final area of the lot= Total Area of the lot - Area of the stadium
Final area of the lot= -
=> Final area of the lot = (Option A)
