Answer:
Area = 90 cm²
Perimeter = 53 cm
Step-by-step explanation:
area and perimeter of the given diagram
area = 1/2 * base * height
where base = 15 cm
height = 12 cm
plugin values into the formula
area = 1/2 * 15 * 12
area = 90 cm²
Perimeter = add up all sides (AB + AC + BC)
where side BC = √(5² + 12²)
BC = 13 cm
Perimeter = 25cm + 15 cm + 13 cm
Perimeter = 53 cm
