Antonio is building a deck around his pool. The pool measures 9 feet by 12 feet, and he wants the deck to have the same width on all 4 sides of the pool.
A 9-foot-by-12-foot rectangle inside a larger rectangle. The distance between the outer edges of the 2 rectangles is labeled w.
Dont worry bout the piccc
The combined area of the pool and deck will be 270 square feet.
Which equation represents the combined area of the pool and the deck?
Answers
(9+w)(12+w)=270
(9×12)(2w+2w)=270
(9+2w)(12+2w)=270
(9+w^2)(12+w^2)=270
(9+2w)(12+2w)=270
because each dimension is increased by w on both sides
