He has 100 meters of chicken wire to build the perimeter.
What should the dimensions of the fence be of the length is 5 more than the width?
:
But he has no "duck wire"! (just joking)
:
Let x = the width
then it says the length is 5 more than the width, therefore
(x+5) = the length
:
The perimeter equation: 2L + 2W = P
therefore:
2(x+5) + 2x = 100
2x + 10 + 2x = 100
4x = 100 - 10
4x = 90
x =
x = 22.5 m is the width
and
22.5 + 5 = 27.5 m is the length
:
:
Check this by finding the perimeter
2(27.5) + 2(22.5) =
55 + 45 = 100
