How do you find the perimeter and area of a square with a width of 4 and length of 5

To find perimeter, you need to add all of the edge's length together. SO you have to add 4+4+5+5 since it has two of each.
The perimeter is 18in
To find area, you need to use length times width. Which means you would need to do 5*4
The area is 20 squared

If you added it all up the total is 20 squared

Ithink the answer would be knew
