Answer:
183 cm^2
Step-by-step explanation:
the line through the shape line means that they are equivalent meaning the side that is empty not making the trapezoid would be 9 as well. moving the 3 over since it is right next to it. 3 times 9 equal 27cm^2. later we are gonna use this number to subtract
then make a different equation with 3+9 to the the full height of the trapezoid pretending it is not missing anything. 3+9=12
then use the formula to find the area of the trapezoid which is 1/2(h)(b1+b2)
add the 2 bases together to get 35. how did i get 35. 12+14=26 yes then include the 9 to get 35.
1/2(height=12)(35)=6(35)=210cm^2
then you used 210-27 to get 183cm^2
