| It is known from the condition that the side of the triangle is 24 cm. It is also known that the height drawn to it is 2 times less than the side. We need to calculate the area of the rectangle.
Let’s start by recalling the formula for calculating the area of a triangle in terms of the side and the height dropped on it.
S = 1/2 * a * ha.
The area of a triangle is equal to half the product of a side by the height lowered to that side.
We are looking for the length of the height:
ha = 24: 2 = 12 cm.
Substitute the values and calculate:
S = 1/2 * 24 * 12 = 144 cm ^ 2.
