Answer:
=6cm2
Explanation:
A very frequently observed Pythagorean triplet is :
3,4,5
This triplet perfectly fits the conditions provided in the question as :
Perimeter : 3+4+5=12cm
and, 5cm perfectly fits as the hypotenuse(as it is the largest of all sides)
So it is a right angled triangle of base and height: 3,4
Area of a right angled triangle :
area=12(base.height)
=12(3.4)
=6cm2
