Question

if a line 3x-4y=lambda cuts the circle x^2+y^2-4x-8y-5=0 in to two points then limits of lambda are
​

Answer 1

Answer:

Let the shorter side be x

longer side be 3x

third side be 3x -2

perimeter= 61cm

so,

3x+x+3x-2=61

7x-2= 61

7x=63

x= 63/7

hence the shorter side length is 9 cm.
