Complete question
Jimmy is putting up a fence around his rectangular garden. One side of the garden is 20 feet long, and b represents the width, How much fencing material will he need.
To get the amount of fencing material needed, we will find the perimeter of the fence
perimeter of the fence = 2(L+W)
L is the length
W is the width
Given
Length = 20feet
Width = b feet
perimeter of the fence = 2(20+b)
perimeter of the fence = 2(20) + 2b
perimeter of the fence = 40+2b cm
Hence the amount of material needed will be (40+2b)cm

Answer:
A = 1 , 1 , 
Step-by-step explanation:
Given equation as
(2a -5) (a² -2a +1) = 0
Or, (2a - 5) (a - 1 )² = 0
Or, (2a - 5) (a - 1) (a - 1) = 0
So, value of a are :
2a - 5 =0, a - 1 =0, a- 1 = 0
i.e a =
and a = 1 , 1
