Question

El jardín de Lucia tiene forma de trapecio. Las bases miden 50 y 35 metros y la altura 22 metros.si por cada metro cuadrado planta dos rosales cuantos rosales tendrá en el jardín?

Answer 1

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

$A=\frac{(B+b)h}{2}$

Where $B=50m$, $b=35m$ and $h=22m$. Replacing these values, we have

$A=\frac{(50+35)22}{2}=\frac{(85)22}{2}=85(11)=935 \ m^{2}$

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

$n=935 \ m^{2} \times \frac{2 \ bushes}{1 \ m^{2} } =1,870 \ bushes$

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