In a square ABCD, if BC = (3x + 4) cm and CD = (5x - 2) cm, the length of AB is:
There is a quadrilateral ABCD with AB=4 cm, BC= 3cm, AD= 2cm, CD= 2cm and angle B=90∘. Can such a quadrilateral exist? Explain. [2 MARKS]
In the given figure, the circle touches the sides AB, BC, CD and DA of a quadrilateral ABCD at the points P, Q, R, S respectively. If AB = 11 cm, BC =x cm, CR = 4 cm and AS = 6 cm, the value of x is
