Question

PLEASE HELP!!! Area of trapezoids and triangles ​

Answer 1

I want to believe 30...?

Answer 2

Answer: 54 square inches and 18 square inches

Explanation:

The formula for the area of a trapezoid is the sum of the top and bottom bases divided by 2, multiplied by the height.

In the first picture the bases are 6 and 12, and the height is 6, so the formula would look like this:

$\frac{6+12}{2} *6$

=$\frac{18}{2} *6$

=$9*6$

=54

54 $in.^{2}$ is the answer to the first problem.

Following the same method, we can do the next problem the same way:

$\frac{4+8}{2} *3$

=$\frac{12}{2} *3$

=$6*3$

=18

18 $in.^{2}$ is the answer to the second problem.
