<h2>Answer: </h2>
1. <u>Area = b × h</u>
A = 5 × 3
A = 15cm².
2. <u>Area = ½(a + b) × h</u>
A = ½(9 + 15) × 15
A = ½ × 24 × 15
A = 12 × 15
A = 180mm².
3. <u>Area = 2(l × b) + l × b</u>
A = 2(12 × 4) + 6 × 3
A = 2 × 48 + 18
A = 96 + 18
A = 114m².
3384 because .88 times 1800 is 1584 and you have to add that to 1800 making it 3384 (or the questions is really easy and its just 1800.88)
