Genny has a square shaped deck in her backyard with the dimensions 15 ft x 15 ft. She plans to enlarge the deck by adding the same amount to the length and width of the current deck. If the length of the addition is a, which equation would provide the new area after the deck enlargement?

• Area = (15a)²

• Area = 15² + a

• Area = 15² + a²

• Area = (15+a)²

• Area = 15a²

Genny has a square shaped homemade rug in her bedroom with the dimensions 5 ft x 5 ft. She plans to enlarge the rug by adding the same amount to the length and width of the current rug. If the length of the addition is a, which equation would provide the new area after the rug enlargement?

• Area = (5+a)²

• Area = 5² + a

• Area = 5² + a²

• Area = (5a)²

• Area = 5a²
