A rectangle is no more than six inches wide, and its perimeter measures 28 inches.?

Question

At least how long is the rectangle?

Answer 1

First you have to realize that the maximum width of the rectangle would result in the shortest length, which is your question. So start with that...

6 inches wide...

Two of the four sides would be six inches, so adding those together gives you 12 inches worth of the perimeter. So...

28 - 12 = 16

There are two sides left... so divide the remainder above by two, and...

16 / 2 = 8

The other answers were right, of course. I just thought you'd benefit from seeing it worked through.

Answer 2

By definition a rectangle is the same length on opposite sides. If it is no more than 6 inches wide, (that would account for no more than 12 inches of the perimeter, leaving no less than 16 inches of perimeter to be accounted for). The opposing sides of the rectangle can be no less than 8 inches.

Answer 3

At one extreme, the sides are 6+8+6+8 = 28.
At the other extreme, the sides are 0+14+0+14 = 28.

Answer 4

8 inches

Answer 5

Let x = length.

2(6 + x) = 28
12 + 2x = 28
2x = 28 - 12
2x = 16
x = 16 /2
x = 8

Proof:
2(6 + 8) = 28
2 * 14 = 28
28 = 28

Answer 6

at least 8 inches long.

28= 2w +2l
28= 2(6) +2l
16=2l
l=8

Answer 7

It's minimum length would be 8 inches long.

If it was 6" wide, then the length would be 8" (2X6+2X8=28)

Answer 8

4 aspects. aspects come 2 pairs (length and width) of equivalent quantities total of all aspects =28 or greater desirable a million section = or below 6 (therefor 2 aspects = or below 12) 28-12 = minimum total of alternative 2 (length) aspects (28-12)/2=minimum length of a million section. do the rest your self I in user-friendly terms help no longer do for you.

Answer 9

A 6x8 inch rectangle would be the smallest length configuration.

Answer 10

8 in.
