Hi!
So what you want to do is to find the perimeter add the sides up 4 times or mutiply 3.5 and 4. It's the same thing
Perimeter: 3.5*4= 14
For area multiply 2 sides and only 2 sides which are the length and width
Area: 3.5 * 3.5 = 12.25
Hope this helps!!
for the perimeter you add 3 1/2 four times of multiply it by 4 and for the area you do 3 1/2 times 3 1/2
