How many yards of fence does the playground have? ** 27 * 4 = <<27*4=108>>108 yards
How many yards of fence does the garden have? ** 2 * (12 + 9) = <<2*(12+9)=42>>42 yards
How many yards of fencing do the playground and garden have together? ** 108 + 42 = <<108+42=150>>150 yards
How many yards of fencing do the playground and garden have together? ** The playground and garden have a combined fence length of 150 yards.
