Answer from: trietvo112200

Length 2x

Width x

Perimeter = 2x + x +2x + x = 72

6x =72

x = 72/6

x = 12 cm

Solution:

Length = 2x = 2(12) = 24cm

Width = x >12cm

Perimeter = 24cm + 12cm + 24cm + 12cm = 72cm

Answer from: fredo99

So,

Let l represent the length and w represent the width.

The first statement translates to:
2l + 2w = 72

The second statement translates to:
l = 2w

We will use substitution, as this is the easiest method.
2(2w) + 2w = 72

Distribute.
4w + 2w = 72

Collect Like Terms.
6w = 72

Divide both sides by 6.
w = 12

l = 2w
l = 2(12)
l = 24

Check.
2(24) + 2(12) = 72
48 + 24 = 72
72 = 72 This checks.

Length = 24 cm
Width = 12 cm

Answer from: Quest

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
