Answer:
The answer is six.
Step-by-step explanation:
For a number to be divisible by nine means that the sum of the digits must be equivalent to a multiple of nine.
The perimeter of a shape is the sum of its side lengths
The corresponding side length for shape B is 20 feet
<h3>How to determine the length</h3>
The length-perimeter ratio is given as:
Ratio = Length : Perimeter
For both shapes, we have:
12 : 36 = Length : 60
Express as fraction

Multiply both sides by 60


Hence, the corresponding side length for shape B is 20 feet

Its - 3/2 if you need to know how I solved it, lemme know :)
Let the number be n. Then
n^2 - (n/2)^2 = 108.
n
From this we get n^2 - (---- )^2 = 108.
2
Mult. both terms by 4, with the result 4n^2 - n^2 = 432
Then 3n^2 = 432, and n^2 = 144. n could be either 12 or -12. You must check both answers by subst. them into the original equation.
