If the length of the side of the square is 12 cm, then we find its area.
We know that the area of a square is equal to the square of its side, that is, it is necessary to multiply 12 cm by 12 cm.
12 cm * 12 cm = 144 cm2 – the area of this square.
If it is said that the area of a triangle is 9 times less than the area of a square, then we find what the area of a triangle is equal to.
Divide 144 cm2 by 9.
144 cm2: 9 = 16 cm2 is the area of the indicated triangle.
Answer: the area of the indicated triangle is 16 square centimeters.
