Answer:
base = 12cm
height = 18cm
Step-by-step explanation:
the ratio of base and height is 2:3, so there is a common number which can divide both base and height and give outcome of 2 and 3. Let's take that number x. so the value of base = 2x and height = 3x.
area of triangle = (1/2)*h*b
108cm² = (1/2)*3x*2x
108cm² = 3x²
x² = 108cm²/3 = 36cm²
x = root of (36cm²)
x = 6cm
base = 2x = 2*6cm = 12cm
height = 3x = 3*6cm = 18cm
