The dimensions of the triangle is
- height of the triangle = 8 feet
- base of the triangle = 26 feet
how to find the length
We use the area of triangle, given by the formula
= 1/2 base * height
where area = 104, height = x
104 = 1/2 (2x + 10) * x
104 = x² + 5x
x² + 5x - 104
using calculator to solve
x = -13 or 8
We take the positive value x = 8
The height of the triangle = 8 feet
The base of the triangle = 2(8) + 10 = 26 feet
