Andreyy89

9514 1404 393

Answer:

  7.5 square units

Step-by-step explanation:

The formula for the area of a trapezoid is ...

  A = 1/2(b1 +b2)h

where b1 and b2 are the lengths of the parallel bases, and h is the perpendicular distance between them.

Here, the bases are TR = 1 and PA = 4. The height is 3 units, so the area is ...

  A = (1/2)(1 +4)(3) = 15/2 = 7.5 . . . . square units
