Answer 2

Answer:

the height of triangle = 30cm

Step-by-step explanation:

given that:

area of the triangle = 270 cm²

base of triangle = b = 18 cm

we know that :

area = (1/2)(b)(h)

where b = base = 18cm

h = height of triangle;

substitute value of base in area of triangle formula

area = (1/2)(18)(h) cm

270cm² = (18/2)(h) cm

270cm = 9(h)

9h = 270

h = (270/9)

h = 30cm

the height of triangle = 30cm
