Step-by-step explanation:
Let ABC be a right angled triangle with right angle at B
let AB=5x and BC=3x−1.
Then, area =△ABC=

(Base×Height))
⇒60=

(AB×BC)⇒60=

×5x(3x−1)
⇒120=5x(3x−1)⇒3x

−x−24=0⇒3x

−9x+8x−24=0
⇒(x−3)(3x+8)=0⇒x=3or3x+8=0⇒x=3orx=−

⇒x=3
AB=5x=5×3=15cm and BC=(3x−1)=(3×3−1)=8cm
Now, AC

+AB

+BC

⇒AC

=15

+8

⇒AC

=289⇒AC=17cm
Hence, hypotenuse =17cm
