9,899 = 206x
He divided by 206
He got 48.053 and rounded up to 49
My using the equation, we can see that he is correct.
I think your answer should be 100 cm...
Hope this helps
The length of the shadow is 14.2 m
Right angle triangle:
Right angle triangle has one of its sides as 90 degrees.
The height of the building is the opposite side of the triangle.
The distance from the top of the building to the tip of the shadow is 35 m is the hypotenuse side.
The length of the shadow is the adjacent side of the triangle.
Therefore,
c² = a² + b²
b² = 35² - 32²
b² = 1225 - 1024
b² = 201
b = √201
b = 14.17
b = 14.2 m
Hence the length of the shadow is 14.2 m.

We know that
[scale]=1 in / 30 in
scale=measure in the drawing/measure in the actual
[measure in the actual]=measure in the drawing/scale
the measure in the drawing are
3 in x 4 in
so
for 3 in
measure in the drawing=3 in
[measure in the actual]=3/(1/30)-----> 3*30------> 90 in
for 4 in
measure in the drawing=4 in
[measure in the actual]=4/(1/30)-----> 4*30------> 120 in
the measure in the actual are
90 in x 120 in
1 ft----------> is equal to 12 in
x-------------> 90 in
x=90/12-----> 7.5 ft
1 ft----------> is equal to 12 in
x-------------> 120 in
x=120/12-----> 10 ft
the measure of a bedroom in feet are
7.5 ft x 10 ft
the area=7.5*10--------> 75 ft²
the answer is
<span>the area of the room is 75 ft</span>²
