As you can see from the polygon, 70/10= 7.

The second polygon is an enlargement of the first one. 

Just multiply 4*7 to get the answer. 

4*7= 28

That's the answer!

I hope this helped you!

Brainliest answer is always appreciated!
10 x 7 = 70 
If the shapes are similar then 4 x 7 = 28
28 would be the missing side length
