To find the height of the triangle, we first need to determine the area of the triangle. Since the composite figure has an area of 156 m², and we know that the composite figure consists of a rectangle and a triangle, we can subtract the area of the rectangle from the total area to find the area of the triangle.

Let's assume the height of the triangle is "h". The rectangle has a height of 5 m and a length of 14 m.

Area of the rectangle = height x length = 5m x 14m = 70 m²

Area of the triangle = total area - area of rectangle = 156 m² - 70 m² = 86 m²

Now, we can calculate the height of the triangle.

Area of a triangle = 1/2 x base x height
86 m² = 1/2 x 12 m x h
86 m² = 6h
h = 86 m² / 6
h ≈ 14.33 m

Therefore, the height of the triangle is closest to 14 m.
