Answer:
length = 16 feet
Step-by-step explanation:
Given,
area = 320 sq. feet
breadth/width = 20 feet
let the length be x.
now
area = l × b
now the equation is,
20x = 320
x = 320/20
x = 16
hence, the length of the rectangle is 16 feet
hope this answer helps you dear...take care!
the length is l=16ft.

Option B
Taking the derivative of the residual function, then applying the normal equation:
[a; b] = (X'*X)^(X'*y)
with
X = [1 1; 2 1; 3 1; 4 1; 5 1]
X' is transpose of X
y = [11; 8; 4; 1; 0]
[a; b] = [-2.9 13.5]
