Answer:
- shape: rectangle
- 27.5 square inches
- 1 1/8 inches by 1 2/3 inches
- see attached
Step-by-step explanation:
The drawing scale is ...
1/4" : 1 ft = 1/4" : 12" = 1 : 48
1) The bedroom shape has two pairs of parallel sides and right-angle corners. It is a rectangle.
__
2) The area of the drawing is 20(1/4 in) × (22(1/4 in)) = 440(1/16 in²)
= 27.5 square inches . . . . area of the bedroom on the drawing
__
3) The drawing side of the bed is 1/48 of the bed's actual dimensions, so is ...
54/48 in × 80/48 in = 1 1/8 in × 1 2/3 in . . . . size of the bed on the drawing
__
4) The drawing looks like it may have been made on a 1/4" grid, but there are only 17 grid squares along the side labeled 20 (feet). So, we actually have no good reference for size. Using the dimension marked as 3 feet for reference we estimated the bed size, trying for 4 1/2 by 6 2/3 feet.
When we print the figure to a piece of paper, we have to scale it to 88.1% to make the 20-foot dimension come out 5 inches. Doing that shows our bed outline is about 82 inches long, not 80 inches long. YMMV

Step-by-step explanation:
1) Tangent makes 90 degrees with the radius. Hence
a) Angle ABD = 90-angle BDC = 90-61.3 = 28.7
b) Triangle BCD is isosceles since tangents have equal length.
Hence angle BCD = 180-(61.3+61.3) = 57.4
c) Angle BDC = 57.4 (since triangle BCD is isosceles)
d) Angle BAC and Angle BCD are supplementary. Hence angle BAC = 122,6

2) Arc length of minor arc BC =
b) ARc length of minor arc = circumference -minor arc
= 18.713
