WebFeb 2, 2024 · Set up the formula for the area of a triangle. The formula is , where is the length of the triangle’s base, and is the height of the triangle. [1] 3 Plug the base and height into the formula. Multiply the … WebArea of shaded region = area of outer shape – area of the unshaded inner shape Area of a triangle = ½ bh. Area of outer shape = (½ x 15 x 10) cm 2. = 75 cm 2. Area of unshaded inner shape = (½ x 12 x 5) cm 2. = 30 cm 2. Area of shaded region = (75 – 30) cm 2. = 45 cm 2. Therefore, the area of the shaded region is 45 cm 2. Example 2
