The area of a triangle is 1440 cm^2. the base of the triangle is 5 times the height. what is the height of the triangle

To find the area of a triangle you would use this formula: bh/2 = Area.
If the base is 5 times the height, then 46 wouldn't be the answer.
That would be: 46 x 230 = 10,580
10,580/2 = 5,290 which isn't 1,440.
However if it was 24 we get this: 24 x 5 = 120
24 x 120 = 2,880
2,880/2 = 1,440.
So the answer is: 24cm
