Step-by-step explanation:
We have to find area of verandah
By taking room to be recgtangular in shape,
Length of room =18.5 m
Breadth of room =14 m
Width of verandah=4.5 m
Length of verandah=18.5m +4.5m +4.5m=27.5m
Breadth of verandah =14m +4.5m +4.5m=23m
Now,Area of room = length of room×breadth of room
= 18.5×14
=259 m^2259m
2
Area of room including verandah=length of verandah×breadth of
verandah
= 27.5m×23m
=632.5m^2632.5m
2
Area of verandhah= Area of room including verandah-Area of room
=632.5m^2-259m^2632.5m
2
−259m
2
Area of verandah =373.5 m^2373.5m
