The perimeter of the rectangle is (10x + 18) units.

Area and perimeter of a rectangle

Area of rectangle = length * breadth

Given the following

Area = 4x^2 + 39x – 10

Expand the expression

Area = 4x^2 + 40x - x - 10

Area = 4x(x+10)-1(x+10)

Area = (4x-1)(x+10)

Hence the width of the rectangle is 4x - 1

Perimeter = 2(L + w)

P = 2(4x-1+x+10)
P = 2(5x +9)
P = 10x + 18

The perimeter of the rectangle is (10x + 18) units.
