How to find perimeter:
If you were trying to find the perimeter of a rectangle you would add all the sides together. If you only have the width and length just times them by 2 and add those numbers together.
For a triangle it would be 1/2 the base times the height
How to find the area:
If you were trying to find the area of a rectangle you would multiply the length by the width. For a square you would only need to know the height and then you could divide it by 4 because a square has 4 equal sides.
I hope this helped please mark me as brainliest!!
