It's graph paper time! This workbook contains triangles, parallelograms, and trapezoids of different sizes. Can you calculate their areas?

To find the area of a triangle, you need to know its base and height. The base is any of the triangle's sides you choose, and the height is the perpendicular distance from the base to the opposite vertex (the highest point if the base is the bottom). Once you have these measurements, use the formula: Area = 1/2 * base * height.

To find the area of a parallelogram, a student should understand that they need to use the formula A = base x height (A = b x h). The base (b) is any one of the sides of the parallelogram, while the height (h) is the perpendicular distance from this base to its opposite side.

You can follow a few simple steps to find the area of a trapezoid. First, remember that a trapezoid is a shape with two parallel sides that are different lengths. To find the area, you need to know the lengths of these two parallel sides (called the bases) and the height (the perpendicular distance between the bases). Once you have those measurements, you can use this formula: Area = (1/2) x (Base1 + Base2) x Height. This formula works because you're averaging the lengths of the two bases and multiplying by the height, giving you space inside the trapezoid.
