A trapezium is such that three of its sides have lengths as 9cm, then the length (in cm ) of the fourth side such that the area of trapezium is maximum, is

If the length of three sides of a trapezium other than the base is 10cm each,find the area of the trapezium,when it is maximum,

If the length of three sides of a trapezium other than the base is 10cm each, find the area of the trapezium, when it is maximum.

If the length of three sides of a trapezium other than base are equal to 10 cm, then find the area of trapezium when it is maximum.

A circle is inscribed in a trapezium in which one of the non-parallel sides is perpendicular to the two parallel sides. Then A) the diameter of the inscribed circle is the geometric mean of the lengths of the parallel sides B) the diameter of the inscribed circle is the harmonic mean of the lengths of the parallel sides C) the area of the trapezium is the area of the rectangle having lengths of its sides as the lengths of the parallel sides of the trapezium D) the area of the trapezium is half the area of the rectangle having lengths of its sides as the lengths of the parallel sides of the trapezium

If the length of three sides of a trapezium other than base are equal to 10cm, then find the area of trapezium when it is maximum.

Three sides of a trapezium are each equal to 6 cm. Let alpha in (0,pi/2) be tha angle between a pair of adjacent sides. If the area of the trapezium is maximum, what is th length of the fourth side ?

If length of three sides of a trapezium other than base are equal to 10cm, then find the area of the trapezium when it is maximum.

If length of three sides of a trapezium other than base are equal to 10cm, then find the area of the trapezium when it is maximum.
