This math chapter workbook on "Areas of a Triangle" has many problem-solving exercises where students calculate the area of different types of triangles. Students must remember that to find the area of a triangle, they can use this simple formula: Area = (base x height) ÷ 2. Some problems will give the base and height of a triangle, so kids can easily plug the numbers into the formula to calculate the area. However, this workbook features many more challenging problems, such as when the base and height are less obvious.
