Calculate the area of a triangle if it is 9 times less than the area of a square with a side length of 12cm.

To find out the area of a triangle, you need to find the area of a square. It can be calculated using the formula:

S (square) = a * b, where a – length, b – width.

Since all sides are equal in a square, we calculate the area of the square:

S (square) = 12 * 12;

S (square) = 144 (cm).

By the condition of the problem, the area of a triangle is 9 times less than that of a square. Find out the area of the triangle:

S (triangle) = 144/9;

S (triangle) = 16 (cm).
