SOLUTION: The perimeter of a rectangle is twice the sum of its length/width. The perimeter is 28 meters and length is 2 meters more than twice the width. WHat is the length?
Question 164337: The perimeter of a rectangle is twice the sum of its length/width. The perimeter is 28 meters and length is 2 meters more than twice the width. WHat is the length?
You can put this solution on YOUR website! Let l be the length and w be the width of a rectangle
then perimeter of a rectangle, p=2(l+w)
Given p=28 metres
and l=2w+2 as length 2 metres more than twice the width
so p=2(2w+2+w)=2(3w+2) = 6w+4
28= 6w+4
-4 -4
----------
24= 6w
w=4metres
l=2w+2 = 2*4+2 = 8+2 =10 metres
length of a rectangle is 10 metres
You can put this solution on YOUR website! The perimeter of a rectangle is twice the sum of its length/width. The perimeter is 28 meters and length is 2 meters more than twice the width.
What is the length?
:
Let x = the width
then
(2x +2) = length
:
The perimeter equation:
2(2x+2) + 2x = 28
4x + 4 + 2x = 28
4x + 2x = 28 - 4
6x = 24
x =
x = 4 meters is the width
then
2(4) + 2 = 10 meters is the length

Check in the perimeter
2(10) + 2(4) = 28
