Question

The area of a triangle is 1,440 cm2. The base of the triangle is 5 times the height. What is the height of the triangle?
12 cm
24 cm
46 cm
60 cm

Answer 1

46?

Answer 2

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 which equals 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 = 1,440. Which is our answer.
So the answer is:
B) 24 cm
