Let us assume the age of the son now = x
Then
The age of the man now = 5x
Now we have to calculate the age of the son and father 9 years ago
Age of the son 4 years ago = x - 4
Age of the man 4 years ago = 5x - 4
Then
5x - 4 = 9(x - 4)
5x - 4 = 9x - 36
5x - 9x = -36 + 4
- 4x = - 32
MUltiplying both sides of the equation by -1 we get
4x = 32
x = 32/4
= 8
So the present age of the son is 8 years
Present age of the man = 5x
= 5 * 8
= 40 years
So the present age of the man is 40 years and the present age of the son is 8 years.

Answer:
You just need to find the length of LM and NM and then find the area of semi-circles using the formula πr²÷2
Let the number be x
<span>Then According to the equation : </span>
<span>2(X-4)=3(x+5) </span>
<span>2X-8=3X+15 </span>
<span>-23=3X-2X </span>
<span>X=-23</span>
9(4+6) because you can use distributive property to get the answer
