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

your answer would be 12

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
