What happens to area and perimeter of a triangle when it is moved?
Just moving a triangle, or rotating, or even reflecting (without scaling) a shape will not change its area or its perimeter.
Why is triangle the most strongest polygonal shape?
The rigidity of the triangle derives from the fact that you cannot change any angle in a triangle without also changing the length of at least one side; in any other type of polygon, it is possible to alter the angles of the polygon without changing the lengths of the sides. So if you have a physical object in the form of a triangle, the sides are not going to change their length unless you break them. Other shapes can fold up, but triangles won't.
What is the relationship between wave amplitude and wave length?
The two are not directly related. You can change the amplitude without changing the wavelength, and vice versa.The two are not directly related.

The length and width of a triangle are each multiplied by 4 find how the perimeter and the area of the rectangle change?
As written, that's confusing. The length and width of a triangle wouldn't have any bearing on the perimeter and area of a rectangle unless they overlap in some drawing that only you are looking at. Let's assume you meant rectangle all along. If the dimensions of a rectangle increased 4 times the perimeter would also increase 4 times. The area would increase 16 times. Try it out. A 2 x 3 rectangle has perimeter 10 and area 6. An 8 x 12 rectangle has perimeter 40 and area 96.
Does the choice of the base change the perimeter of the parallelogram?
No, it does not.
