Answer:
Area of walkway = 16(x+4) 
Step-by-step explanation:
Length of the sides of the square outdoor = x feet
Area of the square outdoor = length x length
= x * x
=

The square outdoor is surrounded by 4 feet of walkway. So that,
length of the walkway = (x + 2(4))
= (x + 8)
Area of walkway with outdoor = (x + 8)*(x + 8)
= (
+ 16x + 64) 
Area of walkway = Area of walkway with outdoor - Area of the square outdoor
= (
+ 16x + 64) - 
= 16x + 64
Area of walkway = 16(x+4) 
Answer:
99 minutes total
