Answer:
<h2>Area = 90 cm²</h2><h2>Perimeter = 53 cm</h2>
Step-by-step explanation:
area and perimeter of the given diagram
<u>area = 1/2 * base * height</u>
where base = 15 cm
height = 12 cm
plugin values into the formula
area = 1/2 * 15 * 12
area = 90 cm²
<u>Perimeter = add up all sides (AB + AC + BC)</u>
where side BC = √(5² + 12²)
BC = 13 cm
Perimeter = 25cm + 15 cm + 13 cm
Perimeter = 53 cm
Answer:
34 5/6
Step-by-step explanation:
Convert the mixed numbers into improper fractions:
57/10 × 55/9
We can reduce these fractions by using the greatest common factor, 3
19/2 × 11/3
Multiply
19/2 × 11/3 = 209/6
Convert to mixed number
209/6 = 34 5/6
