What is the area of the figure?

xenn [34]

Answer: 17.5 square yards

================================================

Work Shown:

base = 5 yards

height = 7 yards

The base and height are always perpendicular to one another

area of triangle = 0.5*(base)*(height)

area of triangle = 0.5*(5)*(7)

area of triangle = 17.5 square yards

The other values aren't used. They're likely thrown in as a distraction.
