A small circle in a square in a big circle in a trapezium. Using
the measurements and clue given, find the area of the trapezium.
Three rods of different lengths form three sides of an enclosure
with right angles between them. What arrangement maximises the area
A trapezium is divided into four triangles by its diagonals.
Suppose the two triangles containing the parallel sides have areas
a and b, what is the area of the trapezium?
A farmer has a field which is the shape of a trapezium as
illustrated below. To increase his profits he wishes to grow two
different crops. To do this he would like to divide the field into
two. . . .
The diagonals of a trapezium divide it into four parts. Can you
create a trapezium where three of those parts are equal in area?
