Answer:
[tex]\huge\boxed{\sf Height = 10\ cm}[/tex]
Step-by-step explanation:
Altitude = Height = AD = ?
Base = 8 cm
Area = 40 cm²
[tex]\rule[225]{225}{2}[/tex]
Area = 1/2 (Base * Height)
40 = 1/2 ( 8 * Height)
40 = 4 * Height
Dividing both sides by 4
40 / 4 = Height
Height = 10 cm
[tex]\rule[225]{225}{2}[/tex]
