21 plants are in the garden
Step-by-step explanation:
here , base = 7 m
height = 24 m
Thus , The area of the triangle (garden ) is 84 m ²
he wants 4 plants for each square meter of area.
therefore , for 84 m ² number of plants are
i.e 21 plants
hence , 21 plants are in the garden
Using the distance formula,


Since ABCD has two pairs of opposite congruent sides, it is a parallelogram.
1. -1, 2,8,11
plug the values into the equation and solve
