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

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

1; 35 is the ratio
