Finding the Area of an Isosceles Triangle

Triangle DEF is an isosceles triangle where the lengths of the equal sides are each 12 cm. The base of the triangle, side EF, measures 10 cm. To find the area of triangle DEF, you can use the formula for the area of a triangle:

$$ ext{Area} =\frac{1}{2} imes ext{base} imes ext{height}$$

First, you need to determine the height of the triangle from vertex D to the base EF. Can you calculate the area of triangle DEF?
