Calculate the area of a trapezium where the dimensions are given in the same units When calculating the area of this trapezium, what is the value of \( h \) in the formula? Area \( =\left(\frac{a+b}{2}\right) h \) ![Trapezium with the slanted sides labelled 8cm and 7.5cm. The parallel sides labelled 3cm and 8cm. The perpendicular height labelled 7cm.]() \( 8 \)
