# The width of a rectangle is 3 less than twice the length, x. if the area of the rectangle is 43 square feet, which equation can be used to find the length, in feet The correct answer was given: Brain

the perimeter of abcde is 10 units

step-by-step explanation:

* lets talk about the regular pentagon

– the regular pentagon has five equal sides

– it has five equal angles

– the measure of each interior angle is = 108°

– the perimeter of it = 5 × length of one side

– to find the length of a side whose endpoints are (x1 , y1) , (x2 , y2)

is √[(x2 – x1)² + (y2 – y1)²]

– if x1 = x2, then the line is vertical and its length = y2 – y1

– if y1 = y2, then the line is horizontal and its length = x2 – x1

* now lets solve the problem

∵ abcde is a regular pentagon

– all of its sides are equal in length

∴ ab = bc = cd = de = ea

∵ a = (2 , 1) and e = (4 , 1)

– the y-coordinates of points a and e are equal, then ae is horizontal

∵ the y-coordinates of point a and e = 1

∴ ae is a horizontal side

∴ its length = x2 – x1

∵ x2 = 4 , x1 = 2

∴ the length of ae = 4 – 2 = 2 units

– the perimeter of the regular pentagon = 5 × length of one side

∴ its perimeter = 5 × 2 = 10 units

* the perimeter of abcde is 10 units The correct answer was given: Brain
