Problema Solution
The perimeter of a rectangle is 38 m. The length is four more than two times the width. What is the width?
Answer provided by our tutors
perimeter = 2*width + 2*length
let 'w' represent the width of the rectangle, then '2w+4' represents the length (four more than two times the width)
calculate the width, knowing the perimeter:
38 = 2w + 2(2w+4)
--------------------
--------------------
w=5
The width of the rectangle is 5 m.
