00:33 This is the solution

Step-by-Step Solution

To solve this problem, we need to find the value of x x , given that the area of the triangle is 16 and the base is known to be 4.

  • Step 1: Identify known values.
    We know the area A=16 A = 16 and base b=4 b = 4 .
  • Step 2: Apply the triangle area formula:
    A=12×b×h A = \frac{1}{2} \times b \times h , where h h is the height we need to calculate.
  • Step 3: Solve for height x x .
    Substitute values into the formula: 16=12×4×x 16 = \frac{1}{2} \times 4 \times x .
  • Step 4: Perform the necessary calculations:
    Simplify the equation: 16=2×x 16 = 2 \times x .
    Divide both sides by 2 to solve for x x .

The calculation simplifies to x=8 x = 8 .

Therefore, the solution to the problem is x=8 x = 8 .
