(i)The length of room = 5.5 m and width of the room = 4 m

The length of room with verandah

= 5.5 + 2.25 + 2.25 = 10 m

The width of room with verandah

= 4 + 2.25 + 2.25 = 8.5 m

Area of verandah

= Area of room with verandah – Area of room without verandah

= Area of ABCD – Area of EFGH

= (AB x AD) – (EF x EH)

= (10 x 8.5) – (5.5 x 4)

= 85 – 22

= 63 m^{2}

(ii) The cost of cementing 1 m^{2 }the floor of verandah = Rs 200

The cost of cementing 63 m^{2 }the floor of verandah = 200 x 63 = Rs 12,600
