Asked by Mary

Sharon made a scale drawing of a triangular park. The coordinates for the vertices of
the park are:
(– 10, 5)
(15, 5)
(10, 12)
Her scale is 1 unit = 1 meter.
What is the area of the triangular park in square meters?
How do you find the answer?
Answered by Reiny
A quick sketch shows that your base is 25 units and the height is 7 units

area = (1/2)(25)(7) = 87.5 units^2

or 87.5 m^2
