Question

What is the area of a triangle with a height of 12

Answer 1

The area of a triangle of height h and base b is:

`A=(bh)/(2)`

Solving for b:

`b=(2A)/(h)`

If the height is 15 and the area is 75:

`b=(2(75))/(15)=10`

The area of a triangle of base b = 10 and height h = 12 is:

`A=(10\cdot12)/(2)=60`

Answer: 60
