GATE Architecture Question

GATE Question :

In a residential community of 10000 population 20% are Higher Secondary school going children. The expected enrolment is 80 % and per capita gross floor space required is 3.0 sq m. The ground coverage permissibility is 40 %. Indicate the land area required for the Higher Secondary school building.

(A) 0.85 hectare
(B) 6.0 hectare
(C) 1.2 hectare
(D) 7.5 hectare

Answer: (C) 1.2 hectare

No of students = 10,000 ×20/100 ×80/100 = 1600 students
Floor space required @ 3.0 sq m / capita= 1600 × 3 = 4800 sq m.
Considering the school building only one storey total built up area is 4800 sq m which is 40 % of ground area.
Therefore total land area = 12000 sq m= 1.2 ha
