Question Analysis:
This question asks for the total surface area of a rectangular prism.
The main focus is applying the standard surface area formula for rectangular prisms.

Key Concept Explanation:
Total surface area = 2(lw + lh + wh)
where l = length, w = width, h = height.

Step-by-Step Solution:
lw = 9 × 5 = 45
lh = 9 × 4 = 36
wh = 5 × 4 = 20
Total surface area = 2(45 + 36 + 20) = 2(101) = 202 m²
