Questions & Step-by-Step Solutions

If the area of a triangle is given by the formula A = 1/2 * base * height, what is the area of a triangle with a base of 10 cm and a height of 5 cm?
  • Step 1: Identify the formula for the area of a triangle, which is A = 1/2 * base * height.
  • Step 2: Identify the values given in the question: base = 10 cm and height = 5 cm.
  • Step 3: Substitute the values into the formula: A = 1/2 * 10 * 5.
  • Step 4: Calculate 1/2 of 10, which is 5.
  • Step 5: Multiply 5 (from Step 4) by 5 (the height): 5 * 5 = 25.
  • Step 6: The area of the triangle is 25 cm².
  • Area of a Triangle – Understanding the formula A = 1/2 * base * height to calculate the area of a triangle.
