Answer:
Similarity, eh?
Step-by-step explanation:
First, we need to find the other side of the smaller parallelogram:
So, let's make a proportion!
[tex]\frac{15}{25} =\frac{3}{x} \\15x=75\\x=5[/tex]
So, the length of the of the other side is 5!
Now we need to find the perimeters!
[tex]P_{1} =2(15+25)\\P_{1} =80\\P_{2} =2(3+5)\\P_{1} =16[/tex]
Now to find the difference!
[tex]D=80-16\\D=64[/tex]
So there you go!
Hope this helps!
P.S. Stay Safe!
