69 * 31 = 2,139
so the area of the whole complex as a rectangle is 2,139m but we don't want the whole rectangle since there is a square cut out.
so just subtract the area of the square with the area of the whole rectangle.
12 * 23 = 276 so the little cut out square is 276m. so do 2, 139m - 276m which is 1,863m.

answer is 1,863m

0.86 is 3.06 % of what number (Round to the nearest hundredth.)
polet [3.4K]

Answer:

Let the number be x

3.06% = 0.0306

The above statement is written as

0.0306x = 0.86

Divide both sides by 0.0306

x = 0.86/0.0306

<h2>x = 28.10</h2>

Hope this helps you
