You must apply the following formula to calculate the area a triangle:
A=bxh/2
b=12 inches (the base of the triangle)
h=12.5 inches (the height of the triangle)
When you substitute these values into the formula, you obtain:
A=bxh/2
A=(12 inches)(12.5 inches)/2
A=75 inches²

You already have the area of one triangle. So, you only have to multiply this area by 7, because the seven (7) triangles are congruent, which means that they have the same area:

At=Ax7
At=(75 inches²)(7)
At=525 inches²

What is the area of the 7 sided figure?

The answer is: 525 inches²
