Find the lateral suface area of a regular pyramid with a triangular base if each edge of the base measures 8 cm. and slant height is 4 cm. एक त्रिभुजाकार आधार वाले सम पिरामिड का पृष्ठ क्षेत्रफल ज्ञात कीजिए यदि प्रत्येक भुजा 8 सेमी. है और तिर्यक ऊँचाई 5 सेमी. है ?

Lateral surface area = perimeter of base × slant height. For triangular base with each edge 8cm, perimeter = 3 × 8 = 24cm. LSA = 24 × slant height = 24 × 4 = 96 cm² would be correct, but options suggest a different calculation. The question has inconsistent data (slant height given as 4cm in English but 5cm in Hindi, and answer matches 4cm).
