Homework Progress 14 / 20 Marks

Solution

To find the area of the trapezium, use the formula: \[ A = \frac{1}{2} (a + b) h & \] Substitute the given values: \[ A = \frac{1}{2} (3 + 7) \times 4 & \] Add the lengths of the parallel sides: \[ A = \frac{1}{2} \times 10 \times 4 & \] Calculate the multiplication: \[ A = 5 \times 4 & \] \[ A = 20 \] Therefore, the area of the trapezium is 20 square units.
