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

Step-by-step 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:

`(6+12)/(2) *6`

=
`(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:

`(4+8)/(2) *3`

=
`(12)/(2) *3`

=
`6*3`

=18

18
`in.^(2)` is the answer to the second problem.
