Final answer:
The area is found using the formula (Diagonal 1 x Diagonal 2)/2, and the answer should be provided in square meters with the appropriate significant figures. Therefore, the correct option is C.
Step-by-step explanation:
To find the area of a kite, you need specific measurements such as the lengths of the diagonals.
The formula for the area of a kite is (Diagonal 1 × Diagonal 2)/2.
Here, diagonal 1 = 9+6
= 15 m
And, diagonal 2= 9+8
= 18 m
Now, the area of kite QRST
= (15×18)/2
= 135 square meter
Therefore, the correct option is C.
