Answer: 3t+4q.
Step-by-step explanation: Triangles have 3 sides, so there will be 3 sides for each triangle in the envelope. This is represented by 3t. Quadrilaterals have 4 sides, so there will be 4 sides for each quadrilateral in the envelope. This is represented by 4q. The total number of sides will be the number of triangle sides and the number of quadrilateral sides together.

Answer:
22 meters
Step-by-step explanation:
What we know:
Side AB is 7 1/2 m long, Side BC is 2 1/4 m long, and Side DE is 1 1/4 m long.
Saying Sides AH and FG are the same as Sides DE and BC respectively, we can add another 3 1/2 m to the perimeter.
If CD, EF and GH are each 1/3 of AB, then 7 1/2 is added again.
7.5 + (2.5 * 3) * (2.25 * 2) + (1.25 * 2)
7.5 + 7.5 + 4.5 + 2.5
15 + 7
The perimeter is 22 meters.
