Area of figure is the total number of 1 square unit in the figure. For a rectangle, it is calculated from the product of its length and its width. For this case, we are given:
Width = x
Length = 7x
Area = x(7x) = 7x^2
The coefficient 7 would mean that the length is 7 times longer than the width, x.
the answer would be (x^2+1)*(x-4)
step by step
x^3+ 4x^2+x+4
X^2(x+8)+ 1*(x+4)
(x+4)(x^2+1)
