Answer:
s = 3, j = 14
Explanation:
The full perimeter is 35.
The given sides we have are 7, 2, 4, 5, and the two missing ones. We will call the two missing ones j and s. (according to your drawing.)
-
The side with the number 7 on it is equal to the side with the number 4 and s.
Can you see that? Even if it's not a direct side, it is under it. (if you can't see that comment below.)
-
Now since we know that we can make an equation:
7=4+s
Subtract 4 on both sides.
3=s.
We now have the length of s, which is 3.
-
Since we now know what s is, we can add them all up once more.
3+5+7+2+4=21
You said the full perimeter is 35. This means j has to be 35-21, which is 14.

This drawing is not drawn to scale, I assume you are drawing this for practice.

Good luck on your test!
