Questions & Step-by-Step Solutions

The area of a triangle is 60 cm². If the base is 10 cm, what is the height? (2019)
  • Step 1: Write down the formula for the area of a triangle: Area = (1/2) * base * height.
  • Step 2: Substitute the known values into the formula. Here, the area is 60 cm² and the base is 10 cm.
  • Step 3: The equation now looks like this: 60 = (1/2) * 10 * height.
  • Step 4: Calculate (1/2) * 10, which equals 5. Now the equation is: 60 = 5 * height.
  • Step 5: To find the height, divide both sides of the equation by 5: height = 60 / 5.
  • Step 6: Calculate 60 divided by 5, which equals 12. So, the height is 12 cm.
