Answer:
n, n+1, n+2
n+n+1+n+2= 87
3n+3 = 87
3n = 87-3
3n = 84
n = 84/3
n = 28
n+1 = 28 + 1 = 29
n+2 = 28 + 2 = 30
the three numbers are 28,29,30
Answer: 5.2834410 and simplify
Answer:
96m²
Step-by-step explanation:
Think of the sclae as 2m per 1cm so you can write that as a fraction and use it as a conversion factor:

As a whole square, the actual dimensions of the dance floor would be:

So each side is actually 10m.
We can use that to solve for the whole square:
A = s²
Where s = side of a square
A = (10m)² = 100m²
Now all you need to do is solve for the are of the missing corner. Consider that missing corner is a right triangle. It's legs are 1cm long and 2 cm long.
If we convert get the actual length it would be: 2m and 4m.
The area of the right triange would be:

Where:
a and b are the two legs of the right triangle (NOT THE HYPOTENUSE, or longest side)
So:
a = 2m
b = 4m
Now plug that into our formula:

Then now we take the area of the missing side and subtract it from the whole square:
Area of the whole square - Area of the missing corner (right triangle)
100 m² - 4m² = 96m²
