Answer:

Step-by-step explanation: It’s the perimeter of each shape so you add the outside of the shape up. The second question is 11.2 and 12 as the width and length. The 11.2 is the width so on the other side it is 11.2, and the length is 12 so the other side is 12. You then add them all up and get your answer.

joja [24]

Answer:

<h2>20 years old.</h2>

Solution,

Let the age of sister be X

Let the age of boy be 2x

Now,

Five years ago,

 $3(x - 5) = 2x - 5 \\ or \: 3x - 15 = 2x - 5 \\ or \: 3x - 2x = - 5 + 15 \\ x = 10$ 

Again,

Replacing value,

 $age \: of \: boy = 2x \\ \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 10 \\ \: \: \: \: \: \: \: \: \: \: \: = 20$ 

hope this helps..

Good luck on your assignment..
