Answer:

Step-by-step explanation:
We have the right triangle and the trapezoid.
The formula of an area of a right triangle:

a, b - legs
We have the length of the legs 12in and 13.42 in. Substitute:

The formula of an area of a trapezoid:

b₁, b₂ - bases
h - height
We have the length of the bases 18in and 11.75in and the length of the height 6.12in. Substitute:

The area of the figure:

Substitute:

Answer:
<u>58 units</u>
Step-by-step explanation:
I decided that one side is 37 units and another is 2 units, since that would make the area 37 units. (you can also use 74 units and 1 unit)
Then I multiplied 37 by 5/4, which equals a new length of 46.25 units, and I also multiplied 2 by 5/4, which equals a new length of 2.5 units.
Finally, I solve for the area of the triangle:
1/2(46.25 x 2.5) ≈ <u>58 units</u> (rounded to the nearest whole number)
