What is the maximum area of a triangle with a base of 10 cm and height as a function of x? (2020)
  • Step 1: Understand the formula for the area of a triangle, which is Area = 1/2 * base * height.
  • Step 2: Identify the base of the triangle, which is given as 10 cm.
  • Step 3: Let the height of the triangle be represented by 'x'.
  • Step 4: Substitute the base and height into the area formula: Area = 1/2 * 10 * x.
  • Step 5: Simplify the formula: Area = 5 * x.
  • Step 6: To find the maximum area, note that 'x' (the height) can be at most 10 cm, since the height cannot exceed the base in this context.
  • Step 7: Substitute x = 10 into the area formula: Area = 5 * 10.
  • Step 8: Calculate the area: Area = 50 cm².
