Find the area of the trapezium with parallel sides 7 cm and 13 cm, and height 8 cm.

Here are the solutions to the questions:

36. Find the area of the trapezium above

Step 1: Identify the lengths of the parallel sides and the height from the diagram.
The parallel sides are $a = 7 \text{ cm}$ and $b = 13 \text{ cm}$.
The perpendicular height is $h = 8 \text{ cm}$.

Step 2: Use the formula for the area of a trapezium, $A = \frac{1}{2}(a+b)h$.

$$A = \frac{1}{2}(7 \text{ cm} + 13 \text{ cm})(8 \text{ cm})$$

Step 3: Calculate the area.
