The length of a rectangle is 4 centimeters more than twice its width. if the perimeter of the rectangle is 86 centimeters, find the dimensions of the rectangle

width = 13

length = 30

p=2l + 2w

86 = 2(2w+4) + 2w

86 = 4w + 8 + 2w

86= 6w + 8

78 = 6w

13 = w

86 = 2l + 2(13)

86 = 2l + 26

60 = 2l

30 = l

check your work.

l is 4 centimeters more than twice w

twice w = 26

plus 4 = 30

i hope you understand. ask questions if not

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
