when we include the varandah , dimension of the room will be
length = 9.5 + 2×2.5 =14.5 m
wide = 7 +2×2.5 =12 m
area = 14.5 ×12 = 174 m²
and area of room without varandah = 9.5×7 = 66.5 m²
area of the varandah = (174 - 66.5) = 107.5 m²
cost = Rs 60×107.5 = Rs 6450
length = 9.5 + 2×2.5 =14.5 m
wide = 7 +2×2.5 =12 m
area = 14.5 ×12 = 174 m²
and area of room without varandah = 9.5×7 = 66.5 m²
area of the varandah = (174 - 66.5) = 107.5 m²
cost = Rs 60×107.5 = Rs 6450
