    Answer:

    58 units

    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) ≈ 58 units (rounded to the nearest whole number)
