which gives x = 29.29 cm. The area of this triangle is
Now suppose that you have a different right triangle where the base is twice the height. Let the height be h cm then the base is 2h cm and in this case Pythagoras tells that the length of the hypotenuse is √5 h cm. Again since the perimeter is 100 cm
which gives h = 19.1 cm. he area of this triangle is
You are going to need more information to determine the area of the triangle. Penny
