Answer 1

Answer:

Answer is =5.5 metre

Step-by-step explanation:

(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 m2 Read more on Sarthaks.com - https://www.sarthaks.com/108033/a-verandah-of-width-2-25-m-is-constructed-all-along-outside-a-room-which-is-5-5-m-long-and-4-m
