If (s-a)=5cm (s-b)=10cm (s-c)=1cm , find a,b & c Where a,b & c are sides of the triangle.

If in a triangle with sides a, b & c, (s-a)=5cm,(s-b)=10cm&(s-c)=1cm find area of the triangle.

If (s-a)=5,(s-b)=10,(s-c)=1 then find a,b,c

In r_(1)=(A)/(s-a) , if A=12cm^(2),r_(1)=4cm and a=3cm then find s making s as the subject.

The T.S.A. of a cuboid of dimension, l=30cm, b=20cm, c=10cm , is ____

In Figure, there are two concentric circles with centre O . P R and P Q S are tangents to the inner circle from point plying on the outer circle. If P R=7. 5 c m , then P S is equal to (a) 10cm (b) 12cm (c) 15cm (d) 18cm

The radius of a circle is increasing at the rate of 0.1 cm/s. When the radius of the circle is 5 cm, the rate of change of its area, is :a) -pi" "cm^(2)//s b) 10pi" "cm^(2)//s c) 0.1pi" "cm^(2)//s d) pi" "cm^(2)//s
