Question

Calculate area of the triangle if x is 5, height is 6x and base is 3x+4

Answer 1

Answer: 285

Formula for area of triangle:

`image`
(For a = base, h = height)

1. Solve side length from equation:

Height:
6x = 6 * 5 = 30

Base:
3x + 4 = 3 * 5 + 4 = 19

2. Replace numbers to equation:


`image` 285

So the answer is
`\underline{285}`
