Question Analysis
This question involves calculating surface area of a rectangular pyramid, where the vertical height is given, not the slant height.
The main focus is using the Pythagorean Theorem to find slant height, then computing lateral area.

Key Concept Explanation
Surface Area = Base Area + Area of 4 triangle faces
Slant height is found using:
  slant height² = vertical height² + (½ base side)²

Step-by-step explanation
Base Area:

– Short side (half = 3):

– Long side (half = 2):

Lateral Faces:
2 short triangles:
