It seems you've uploaded an image of a geometry and algebra worksheet focused on perimeter calculations. Let's go through the problems in the image:

Problem Breakdown:

1. Red Triangle:

   • The sides are labeled $x$, $x+4$, and $x+6$.
   • Perimeter expression: The perimeter $P$ of a triangle is the sum of the lengths of its sides. $P = x + (x + 4) + (x + 6) = 3x + 10$

2. Blue Triangle:

   • The sides are labeled $a$, $a+5$, and $a+5$.
   • Perimeter expression: $P = a + (a+5) + (a+5) = 3a + 10$

3. Green Rectangle:

   • The dimensions are $n$ and $n+2$.
   • Perimeter expression for a rectangle: $P = 2n + 2(n + 2) = 2n + 2n + 4 = 4n + 4$

4. Pink Right-Angle Triangle:

   • The sides are labeled $y+1$ and another side (which is not fully visible). If the missing side information is available, we can calculate the perimeter similarly.

Would you like further clarification on any of these problems or a solution for the remaining problems in this image?

Here are 5 relative questions to deepen your understanding:

1. How do you determine the perimeter for different polygons?
2. Can you generalize a formula for the perimeter of any regular polygon?
3. How would changing the side lengths affect the perimeter of a shape?
4. What would happen to the perimeter if all side lengths doubled?
5. How would you calculate the perimeter of a shape with curves like a circle?

Tip: Always simplify the perimeter expressions to their lowest terms to avoid errors during calculation.
