AB, BC and AC are the tangents of the circle. If AR = 5cm, BP = 4cm and BC 10cm, find the perimeter of the triangle.

AB,BC,CD and AD are the tangents of the circle.If AP=x,BP =y, CR =z, SD =W then show that the perimeter of the quadrilateral ABCD is 2(x+y+z+w).

In /_\ABC ,AB=8 cm, BC =10cm and /_B = 60^@ :- Find the area of the triangle /_\ABC .

Corners of a square are. on a circle. If the length of one side of square is 10 cm, find the perimeter of the circle.

In /_\ABC , AB=20cm /_A=30^@ , AC=12 cm :- Find the area of the triangle.

Triangle ABC' and 'triangle PQR' 'are similar triangles. If 'AB=6 cm, BC=7 cm, PQ=9 cm','PR=6 cm', find other sides of the triangles.

In the figure given below P, Q, R are the mid points of the sides of AB, BC and AC of the triangle ABC . The area of the triangle ABC is 60 sq.cm. find the area of the parallelogram APQR.

In /_\ABC ,AB=10cm.AC= 8 cm, /_A = 45^@ :-Find the area of the triangle.

ABCD is a quadrilateral such that all of its sides touch a circle. If AB = 6cm, BC = 6.5cm and CD =7cm,then And the length of AD.

In triangle ABC, AB=10 cm, AC=20 cm and /_ A=135^circ a) Compute the-area of the triangle.
