Respuesta :

We can easily find the area of the square so lets solve that first.
10x14= 140

Now we need to solve the triangles outside the square
14x4=56
This would the area of a rectangle/square and thats a triangle so cut it in half
56/2=28

Square (140) + 2 Triangles (28 + 28) = 196


Area of a trapezium = (h/2)[a + b]
h = 14
a = 10
We need to find b!
B = 10 + 4 + 4 = 18
So,(14/2)[10 + 18]
          7    *    28       =  196 square inches.

Hope this helps :)
