QuestionInstructions Solve the following problem and select your answer from the choices given.
Question
The area of the triangle above is 21 . What is the value of $x$ ? 3 6 7 11

Studdy Solution
Verify the solution by substituting $x = 6$ back into the area formula:
Base = $x + 1 = 6 + 1 = 7$
Height = $x = 6$
Calculate the area:
$$\text{Area} = \frac{1}{2} \times 7 \times 6 = \frac{1}{2} \times 42 = 21$$
The calculated area matches the given area, confirming that the solution is correct.
The value of $x$ is:
$$\boxed{6}$$
