1.	squareA square room is surrounded by a verandah of width 2 m. The area of the verandah is 64 m'. Find thearca of the room.
Answer» Verandah area Av = 64 m^2Verandah width = 2 m Let square room length = sThen, Area of room Ar= ssArea of outer space including room Ao = (s + 4)(s + 4) Av = Ao - Av64 = (s + 4)(s + 4) - ss64 = 8s + 168s = 64 - 16s = 48/8s = 6 Area of room = 6*6 = 36 m^2

squareA square room is surrounded by a verandah of width 2 m. The area of the verandah is 64 m'. Find thearca of the room.

Answer»

Verandah area Av = 64 m^2Verandah width = 2 m

Let square room length = sThen, Area of room Ar= s*sArea of outer space including room Ao = (s + 4)*(s + 4)

Av = Ao - Av64 = (s + 4)*(s + 4) - s*s64 = 8s + 168s = 64 - 16s = 48/8s = 6

Area of room = 6*6 = 36 m^2
