Problema Solution
The length of a rectangle is 7 more than 3 times the width.if the perimeter is 58 inches find the dimensions of the rectangle
Answer provided by our tutors
let 'w' represent the width, then '3w+7' represents the length
perimeter = 2(length + width)
58 = 2(w+3w+7)
58 = 2w + 6w + 15
44 = 8w
w = 44/8 = 5.5
3*5.5 + 7 = 23.5
the width of the rectangle is 5.5 inches, its length is 23.5 inches
