Assume that the dimensions of the room in the plan are a (width ) by b (length),
such that a*b=30.
Since the scale is 1:100, a represents 100a, and b represents 100b.
So the actual dimensions are 100a by 100b.
The area is 100a*100b=a*b*10,000=30*10,000=300,000 (square units)
Answer: 300,000 (square units)
Answer:for the second question/First question that is unsolved it's
350
for the second unsolved question its200
for the third unsolved one its 550
Step-by-step explanation:
The first one is wrong 55%=35
45%=25
35x10=350
25x8=200
add it =550
cot x = cos x / sin x
cot x = .85 / .52 = 1.6346
