Answer:
42 plants
Step-by-step explanation:
Dimensions are missing.
Suppose a right triangle has a base of length 7yards  and a height of 24 yards.
As you know, Area of triangle can be determined by
Area of triangle 'A'=  1/2 x b x h = 1/2 x 7 x 24
A= 84 yards²
Now she wants 2 plants for each square yard of area
therefore, if the area is 84 yards²:
number of plants are 84/2=> 42 plants
Thus, She wants 42 plants in the garden
