Answer:

Let x be the base of the triangle, then the altitude will be (x−7).

By Pythagoras theorem,

x

+(x−7)

=(13)

x

−12x+5x−60=0

(x−12)(x+5)=0

x=12,x=−5

Since the side of the triangle cannot be negative, so the base of the triangle is 12cm and the altitude of the triangle will be 12−7=5cm.
