They should also be confident when calculating the area of a square, a right angled triangle, a rectangle or an L-shape and in converting between mm 2, cm 2 and m 2. They will now be exposed to three-dimensional, or 3D shapes, and shown how to calculate their area....Since the areas of two congruent triangles are identical to the area of a rectangle, we may have the formula A = 1 ⁄ 2 b • h if we want to determine the area of a triangle. When we’re using the formula for triangles, if we want to find its area, it’s key to identify the base and the corresponding height (perpendicular to its base).
