In a site map, a rectangular residential plot measures 150 mm × 40 mm and the width of the front road in the map measures 16 mm

Q. In a site map, a rectangular residential plot measures 150 mm × 40 mm, and the width of the front road in the map measures 16 mm. Actual width of the road is 4 m. If the permissible F.A.R. is 1.2, the maximum built-up area for the residential building will be___________m².

1. 150 sqm
2. 450 sqm
3. 350 sqm
4. 650 sqm

The map is scaled 4000/16 times i.e 250 times, as inferred from

the dimensions of the road. Thus the actual area of plot = (0.15 × 250) × (0.04 × 250) sq m = 37.5 × 10 = 375 sq m

Since, the Permissible F.A .R. i s 1.2, the maximum built -up area for the residential building is 1.2 × 375 sq m = 450 sq m
