First, we determine the height of the isosceles trapezoid using Pythagoras theorem.
The two parallel sides of the trapezoid are 8 Inits and 4 units respectively.
Area of a trapezoid
Area of the trapezoid
For an equilateral triangle of side length s.
Area
Side Length of the smaller triangle, s= 4 Units
Therefore:
Area of the smaller triangle
Therefore, the ratio of the area of the smaller triangle to the area of the trapezoid
