The length of a rectangle is 5 centimeters more than twice the width. The perimeter is 82 centimeters. Find the length and width.

The length is 29 cm while the width is 12cm

Step-by-step explanation:

Given that the length l of a rectangle is 5cm more than twice the width w then

l = 5 + 2w

If the perimeter p of the rectangle is 82cm, recall that the perimeter p of a rectangle is given as

p = 2(l + w)

substituting for l into the equation

82 = 2(5 + 2w + w)

82 = 2(5 + 3w)

Divide both sides by 2

41 = 5 + 3w

41 - 5 = 3w

36 = 3w

Divide both sides by 3

w = 12cm

recall that

l = 5 + 2w

l = 5 + 2(12)

l = 5 + 24

l = 29cm

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
