Brandy has a rectangular wooden deck that measures 7 feet by 12 feet. She builds an addition to the deck that is 4 feet longer. What is the perimeter of her deck now?

Answer 1

The new length of the deck is 12+4=<<12+4=16>>16 feet.
The dimensions of the deck are now 7 feet by 16 feet.
The perimeter of the deck is 2*7+2*16=14+32=<<2*7+2*16=60>>60 feet. Answer: \boxed{60}.
