What is the length of the rectangle if the perimeter is 134m and the length is 7 more than half the width?

Let the length be (1/2x+7) and the width be x:
Perimeter = 2(length+width) = 134
2(1/2x+7+x) = 134
Multiply out the brackets:
x+14+2x = 134
Collect like terms and subtract 14 from both sides:
3x = 120
Divide both sides by 3:
x = 40
Therefore: length = 27 meters and width = 40 meters
Check: 27+27+40+40 = 134 meters
