I attempted this already, What is the area of the trapezoid?
larisa [96]

Answer:

40.5 cm

Step-by-step explanation:

So think about it what is the Formula for a Trapezoid? Well it's h(b1+b2)/2! So we use this formula and place the numbers in there! When you're done you should have this: 6(9+4.5)/2. Now we will do <u>PEMDAS</u> (parenthesis, exponents, multiplication, division, addition, subtraction). from left to right. So we first do 9+4.5. That equals 13.5. Then we times that by 6, which is 81. Then we finally divide it by 2. Then there's your answer! :D
