Question

Hi can you please help me​

Answer 1

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
