Answer:

Perimeter of the room = 63 ft

Area of the room = 202.5 ft²

Explanation:

Scale of drawing = 1 in to 4.5 ft

Length of the room in the drawing = 5 in

Actual length of room = 5*4.5 = 22.5 ft

Width of the room in the drawing = 2 in

Actual length of room = 2*4.5 = 9 ft

Perimeter of the room = 2(L + W)

= 2(22.5 + 9)

= 2(31.5)

Perimeter of the room = 63 ft

Area of the room = L*W

Area = 22.5*9

Area of the room = 202.5 ft²
