Problema Solution
The length of a new rectangular playing field is 7 yards longer than double the width. If the perimeter of the rectangular playing field is 368 yards, what are its dimensions?
Answer provided by our tutors
width= x
lenght= 2x+7
so, perimeter= 2(length + width)
368 = 2(2x+7+x)
184= 3x+7
so, 177=3x
x= 59 yards
so, length= 125 yards
and width= 59 yards.
