Questions & Step-by-Step Solutions

If the height of an isosceles triangle is 12 cm and the base is 10 cm, what is the area of the triangle?
  • Step 1: Identify the formula for the area of a triangle, which is Area = (1/2) * base * height.
  • Step 2: Substitute the values into the formula. Here, the base is 10 cm and the height is 12 cm.
  • Step 3: Calculate the area by multiplying the base and height: 10 * 12 = 120.
  • Step 4: Divide the result by 2 to find the area: 120 / 2 = 60.
  • Step 5: Conclude that the area of the triangle is 60 cm².
  • Area of a Triangle – The area of a triangle can be calculated using the formula (1/2) * base * height.
