22 meters.
The perimeter is 42 metres.
width = (x + 4) cm length = [(x + 4) + (x + 7)] cm Rectangle Perimeter = 2[(x + 4) + (x + 4 + x + 7)] cm Rectangle Perimeter = 2[(x + x + x) + (4 + 4 + 7)] cm Rectangle Perimeter = 2(3x + 15) cm Rectangle Perimeter = (6x + 30) cm
The perimeter is the distance around, the sum of the sides. A 5 x 7 or a 4 x 8 rectangle has a perimeter of 24.
7 + 4 + 7 + 4 = 22 feet
