Answer:

Lucia is able to plant 1,870 rose bushes in her garden.

Step-by-step explanation:

We know that Lucia's garden has a trapezoid form, where its bases are 50 and 35 meters each and its height is 22 meters.

The area of a trapezoid is defined as

[tex]A=\frac{(B+b)h}{2}[/tex]

Where [tex]B=50m[/tex], [tex]b=35m[/tex] and [tex]h=22m[/tex]. Replacing these values, we have

[tex]A=\frac{(50+35)22}{2}=\frac{(85)22}{2}=85(11)=935 \ m^{2}[/tex]

Therefore, the area of the garden is 935 square meters.

Now, if Lucia plants two rose bushes per each square meter, then 935 square meters would be equivalent to

[tex]n=935 \ m^{2} \times \frac{2 \ bushes}{1 \ m^{2} } =1,870 \ bushes[/tex]

Therefore, Lucia is able to plant 1,870 rose bushes in her garden.
