Answer:
20
Step-by-step explanation:
nPr = n!/(n-r)!
5P2 = 5!/(5-2)!
= 5!/3!
= 5×4×3!/3!
= 5×4
= 20
P=32cm
A= 64cm^2
Step by Step
Formula(Perimeter): P=s+s+s+s
S=side P=perimeter
P=8*4
P=32
Formula(Area for Square): A=s^2
A=Area s=side
A=8^2
A=84
Answer:
x=64
Step-by-step explanation:
x=8
(x)^2=8^2
x=64
