Question

Work out the height of this triangle with base,

b
= 8.6mm and area,
A
= 256.28mm2.

Answer 1

`59.6` mm

Explanation:

We know that the base times the height divided by two is the area, so we have that
`(8.6*h)/2=256.28`.

We can multiply both sides by
`2` to get
`8.6*h=512.56`.

Lastly, we divide by
`8.6` on both sides to get
`h=512.56/8.6`.

This simplifies to
`\boxed{h=59.6}` mm!
