Answer:
Let ABC be the right angled triangle.
Given, Area of the triangle = 54 cm^2
Length of one of its side, BC = 12 cm
We know that, Area of a right angle triangle = 1/2 × b× h
= > 54 = 1/2 × AB × BC
=> 54 = 1/2 × AB × 12
=> AB = 9
Again, APPLYING PYTHAGORAS THEOREM :-
AC^2 = AB^2 + BC^2
= 9^2 + 12^2
= 81 + 144
= 225
Hence, AC = 15 cm
The length of the other side i. e. the Hypotenuse, AC = 15 cm. The length of the altitude, AB = 9 cm.
