Step-by-step explanation:
Lateral SA = area of the 4 triangles
Formula to be used :-
Area (triangle) = 1/2bh
=> 4 x 1/2 x 9 x 12
=> 108 x 2
=> 216 cm²
Total SA = LSA + area of the square
Formula to be used :-
Area (square) = side length x side length
=> 216 + 9 x 9
=> 216 + 81
=> 297 cm²
<u>The correct option is (D).</u>

I' would say A but C could be a possibility.
Step-by-step explanation:
If you want to take a square root of a square root you will need 2 squares roots,
For example, i want the square root of the square root of 16.
I'll take it first: √16 = 4 and again, √4 = 2
So, the square root of the square root of 16 is 2.
But you can also make a root with index 4.
Because if you do 2.2.2.2 you will take 16.
