Answer:

The correct answer is option D

Explanation:

The lateral area of pyramid is


l * √((w/2)^2 + h^2)  + w * √((l/2)^2 + h^2) \\

Where


l = 42 yd\\w = 42 yd\\h = 38 yd\\

Substituting all these values in above equation, we get -


42 * \sqrt{((42)/(2))^2 + 38^2 } \\ + 42 * \sqrt{((42)/(2))^2 + 38^2 } \\\\= 2 * 42 * 43.41\\= 3647 yd^2\\
