A square outdoor patio with side length x feet is surrounded by a brick walkway that is 4 feet wide. What is the area of the walkway

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)

b is the final answer! : )

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
