In the given figure,ABCD is a quadrilateral in which /_D=90^(@). A circle C(O,r) touches the side AB,BC,CD and DA at P,Q,R and S, respectively.If BC=38cm,CD=25cm and BP=27cm, then find the value of r.

ABCD is a quadrilateral such that angle D= 90^@ . A circle with centre O touches the sides AB, BC and CD and DA at P, Q, R and S respectively. If BC = 40 cm, BP = 28 cm and CD = 25 cm, then what is the radius of the circle is: ABCD एक चतुर्भुज है जैसे angle D= 90^@ । केन्द्र O वाला एक वृत्त क्रमशः AB, BC और CD और DA को P, Q,R और S से छूता है। यदि BC = 40 सेमी, BP = 28 सेमी और CD = 25 सेमी है, तो वृत्त का त्रिज्या क्या है

Figure ABCD is a trapezium of area 24.5 cm^2 . If AD||BC, ∠DAB = 90^(@) , AD = 10 cm, BC= 4cm. If ABE is a quadrant of a circle. Find the area of the shaded region (pi = (22)/(7))

In the given figure, ABCD is a quadrilateral in which /_D=90. A circle C(O,r) touches the sides AB,BC,CD,DA at P,Q,R and S respectively. If BC=38 cm, CD=25 cm, and BP=27 cm, then find the value of r.

In Delta ABC, D, E, F are mid-points of AB, BC, CA respectively and angle B = 90^@ , AB = 6 cm, BC = 8 cm. Then area of Delta DEF (in sq.cm) is

ABC and CDE are right angled triangle. angleABC = angleCDE = 90 ^(@), D lies on AC and E lies on BC. AB = 24 cm, BC = 60 cm . If DE = 10 cm, then CD is:

Find the area of quadrilateral ABCD in which angleB=90^(@) , BC = 32 cm, AB = 24 cm and CD=DA = 25 cm.

In a triangle ABC, angleB=90^(@), D is the midpoint of AC, BD=sqrt117 . Sum of sides of AB & BC is 30 cm. Find the area of triangle ABC.

In the following figure (not to scale), angle DAB + angle CBA = 90^@ , BC = AD, AB = 20 cm, CD = 10 cm, then the area of the quadrilateral ABCD is: निम्नलिखित आकृति (जो पैमाने के अनुसार नहीं है) में, angle DAB + angle CBA = 90^@ , BC = AD, AB = 20 सेमी, CD = 10 सेमी है, तो चतुर्भुज ABCD का का क्षेत्रफल कितना होगा?
