Answer:

7.3

Explanation:

The formula to find the area of a triangle is (1/2)(a)h = A.

Replace the variable h (height) with x.

Isolate the x variable (height) in order to find the height value.

(1/2)(6)x = 21.9

3x = 21.9

x = 21.9/3

x = 7.3

Answer:

x = 7.3

Explanation:

area = base × height / 2

21.9 = 6 × x / 2

43.8 = 6x

x = 7.3
