I’m not really sure how to solve this problem so can someone ? find the area of the shaded region?

Hree you have a small ( the clear triangle) inside  a large one. 
Area = shaded part = area of large triangle - area of the small clear triangle.

Area of a triangle = 1/2 * base * height 
so we have area shaded part = 1/2 * 6 * 9 - 1/2 * 2 * 3
=  27 - 3  = 24 yd^2  Answer
