<h2>Answer: </h2>

1. Area = b × h

A = 5 × 3

A = 15cm².

2. Area = ½(a + b) × h

A = ½(9 + 15) × 15

A = ½ × 24 × 15

A = 12 × 15

A = 180mm².

3. Area = 2(l × b) + l × b

A = 2(12 × 4) + 6 × 3

A = 2 × 48 + 18

A = 96 + 18

A = 114m².

Toni can carry up to 18 lb in her backpack. Her lunch weighs 1 lb, her gym clothes weigh 2 lb, and her books (b) weigh 3 lb each

MrRissso [65]

Toni can carry five books in her backpack. You must start by subtracting the weight of the other required items. Toni's lunch which is one pound and gym clothes which are two pounds. This can be calculated by 18-1-2=15. Toni has 15 pounds left to carry books. She should divide this by the weight of each book, which is three pounds. 15/3=5. Therefore, Toni can carry five books.
