Calculate the area of a trapezium where the dimensions are given in the same units Sally wants to calculate the area of this trapezium using the formula: Area \( =\left(\frac{a+b}{2}\right) h \) ![A trapezium with the parallel sides labelled 5cm and 1cm, the slant height labelled 6cm and the perpendicular height labelled 4cm.]() What is the values of \( h \) ? \( 1 \mathrm{~cm} \)
