Answer:

  180

Step-by-step explanation:

You want to know the number of plants needed in a garden with the shape of a right triangle having side lengths 8 ft, 15 ft, and 17 ft, if there are 3 plants for each square foot.

Area

The two shorter sides of the right triangle comprise the base and height, so the area of Jessica's garden is ...

  A = 1/2bh

  A = 1/2(8 ft)(15 ft) = 60 ft²

Plants

At the rate of 3 plants per square foot, the number of plants needed is ...

  (3 plants/ft²) × (60 ft²) = 180 plants

Jessica wants 180 plants in the garden.
