Correct Answer: 24 cm 2


Solution : The side of the square = $\frac{24}{4}$ = 6 cm
The base of the triangle is 6 cm.
The perimeter of the triangle is 24 cm.
Using the Pythagoras triplets (i.e. 6, 8, and 10).
So, the height of the triangle is 8 cm.
The area of a triangle = $\frac{1}{2}$ × 6 cm × 8 cm
Hence, the correct answer is 24 cm 2 .
