Answer:
The height is 8 cm
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
72 = 1/2 (18)h
72 = 9h
Divide each side by 9
72/9 = 9h/9
8 = h
The height is 8 cm
Answer:
8cm
Step-by-step explanation:
let y represent height
Area of a triangle=½base×height=72cm²
72cm²=½×18cm×y
72cm²=9cmy
72cm²/9cm=9cmy/9cm
8cm=y
