Given the area of a trapezium, calculate a missing dimension The area of this trapezium is \( 40 \mathrm{~cm}^{2} \). What would the perpendicular height, \( h \), of the trapezium be? ![Trapezium with parallel sides of lengths 6cm and 10cm]() \( h=8 \mathrm{~cm} \)
gpt
Believes h in the formula for area of a trapezium stands for half the sum of the parallel sides
