To find the shaded area, you need to find the area of the rectangle, and subtract the areas for the four triangles
Rectangle: A=lw
A=188
A=144
Triangle: I am going to find the area of one triangle and multiply by 4 after since there are 4 triangles
A=1/2bh
A=1/244
A=24
A=8
Since there are four triangles, we do 84 to get 32
The we do the area of the rectangle minus the area of the triangles to find the answer
144-32=112 square inches
Hope this helps
