Question

An square room is surrunded by varemda of width 2sq m.area of varemda is 64 sq m. find area of room

Answer 1

64=area enclosed by veranda-Atea enclosed by room

Area enclosed by veranda = (Side of room + 4 (since veranda is 2 m wide there fore on each side 4 m will be added ))^2

Let side of square=s

Hence 64=( s+4)^2 -s^2

64= s^2 +16+8s-s^2

48=8s

S=6

There fore area =s*s=36sqm
