<u>Given</u>:
Four lines are marked proportion, the length of TW can be determined by

<u>Value of a:</u>
Let us set the proportion for the given lines.
Thus, we have;
  

  
Thus, the value of a is 5.6
<u>Value of b:</u>
Let us set the proportion for the given lines.
Thus, we have;
  

  
Thus, the value of b is 5.
<u>Length of TW:</u>
The length of TW is given by


Thus, the length of TW is 13.6

Answer:
Is not correct. The product not always will be smaller.
Step-by-step explanation:
A fraction could increase a number if you multiply it.  
If the numerator is higher to the  denominator,  it will increase it.  
If the numerator is smaller to the  denominator,  it will decrease it.
<u>For example,</u>
10 x 4/3
For fraction multiplication, multiply the numerators and then multiply the denominators to get
10×4/1×3=40/3= 13,33 
13,33 is higher than 10.
5 x 10/3
For fraction multiplication, multiply the numerators and then multiply the denominators to get
5×10/1×3=50/3
16,66 is higher than 5.
