Answer:

  • 34 cm²

Step-by-step explanation:

Area of trapezoid formula:

  • A = 1/2(b1 + b2)h

Substitute values and find the area:

  • A = 1/2(5 + 12)*4 = 34 cm²

Answer:

34

Step-by-step explanation:

Given the trapezoid formula:

1/2(b1+b2) x h

The first step is to find the bases and height.

1/2(12+5) x 4

The second step is to do what is in the parentheses.

12+5=17

The third step is to divide 17 and 2.

17÷2=8.5

The last step is to Multiply 8.5 and 4.

8.5 x 4 = 34

So your answer is 34 centimeters.
