SUMMARY
The discussion centers on calculating the height of a trapezium given the side lengths AB = (x + 3) cm and DC = (2x − 3) cm, with an area of 15 cm². The area formula for a trapezium, A = ½(a + b)h, is utilized to derive an expression for height (h) in terms of x. Participants emphasize the need to rearrange the area formula to isolate h, leading to the conclusion that further algebraic manipulation is necessary to express h explicitly.
