part A: perimeter is 38
steps: add all 4 sides to get perimeter (the outer length)
9.5×9.5×9.5×9.5=38
equation: p=s^4 or p=s×s×s×s
p stands for perimeter and 4s is the side length being multiple 4 times
part B: area is 90.25
steps:you multiply the length times the width to find are and since a squares sides are all equal you multiply 9.5 times 9.5
equation: L×W= area
