Answer:
Given that:
x = 5 cm
Height = 6x = 6 * 5 cm = 30 cm
Base = 3x + 4 = 3 * 5 cm + 4 cm = 19 cm
The area of a triangle is calculated by half the product of the base and the height.
Area = (1/2) * base * height
Plugging in the values, we get:
Area = (1/2) * 19 cm * 30 cm
Area = 285 cm^2
Therefore, the area of the triangle is 285 cm^2.
I hope this helps!
