Twice the length of a rectangle is equal to four times its width. the perimeter of the
rectangle is 80 inches. find the dimensions of the rectangle.

Let l and w be the length and width of the rectangle. We are given the proportion 2l=4w, which implies l=2w.

The perimeter of a rectangle is given by 2(l+w). We know that the perimeter is 80, and we can plug l=2w to get

Which, in turn, implies that

Question: -4 + 5x -7 = 10 + 3x -2x

⇒ 5x -11 = 10 + x

⇒ 5x - x = 10+11

⇒ 4x = 21

⇒ x = 21/4

Answer is Option D

x = 21/4
