Hello,

nice as problem.

$| If\ a\ number\ x=a_1^{p_1}*a_2^{p_2}*a_3^{p_3}*....*a_n^{p_n}\\ the\ number\ of\ his\ dividers is:\\{p_1+1}*{p_2+1}*{p_3+1}*....*{p_n+1}$
Here x has a power of 5 as divider and a power of 2 as divider (in order to make a power of 10.

$5=5^1*2^0$

$50=5^1*(5^1*2^1)=5^2*2^1$

$500=5^1*(5^2*2^2)=5^3*2^2$

$50 000 000=5^8*2^7$

Numbers of dividers: (8+1)*(7+1)=9*8=72

Answer:

Perimeter of the rectangle=Perimeter of the trapezium

2{(3x+4)+(4x)}=2(5x)+(x-3)+(7x-3)

→2(7x+4)=10x+x-3+7x-3

→14x+8=18x-6

→4x=14

→x=7/2

→x=3.5

The value of x is 3.5 cm
