Answer 2

HERE IS UR ANSWER DEAR,

It accepts the condition of Pythagorean triplets .

c² = a² + b²

= 9² + 12²

= 81 + 144

c² = 225

c. = 15 cm

which is the third side of our triangle

therefore,

we can able to mention the sides as

Base (b) = 9 cm

height (h) = 12 cm

hypotenuse = 15 cm

Area of the triangle = 1/ 2 × b×h

= 1/ 2 × 9 × 12

= 54 cm²
