Problem Analysis

We are given that the length of one side of an isosceles triangle is 17 cm, and the length of the bisector drawn to the base is 15 cm. We need to find the area of the triangle.

Solution

To find the area of the triangle, we can use the formula for the area of a triangle:

Area = (base * height) / 2

In this case, the base of the triangle is the side of length 17 cm, and the height is the length of the bisector drawn to the base, which is 15 cm.

Let's substitute the values into the formula and calculate the area:

Area = (17 * 15) / 2

Area = 255 / 2

Area = 127.5 square cm

Therefore, the area of the triangle is 127.5 square cm.

Answer

The area of the triangle is 127.5 square cm.
