Find the total cost of 12 Series EE Savings Bonds with a face value of $100.

I would go with with 56 cm^2

Step-by-step explanation:

Area of rectangle=L*W,Area of triangle=B*H*1/2

the area of rectangle shows that length times width would equal the area of a rectangle which is one of the shapes from the trapezoid,so 4*9=36 cm

then there are also the base and height of both triangles shown are the exact same so 4*5*1/2=10 cm,4*5*1/2=10cm

the last step is to add all the numbers together,so 10+10+36=56 cm^2
