Question

Sparks garden is a shape of a trapezoid in the dimension are shown below I got in your needs to spread fertilizer over the flower beds each bag of fertilizer he uses covers 240 m^2. would be the number of bags of fertilizers?

Answer 1

ANSWER:

12 bags of fertilizers are needed

STEP-BY-STEP EXPLANATION:

In this case we must calculate the area of the garden that has a trapezoid shape by means of the following formula:

$A=\frac{B_1+B_2}{2}\cdot h$

Replacing:

$\begin{gathered} A=\frac{70+40}{2}\cdot50 \\ A=2750 \end{gathered}$

Now to calculate the number of bags, we must divide the total area by the area covered by each bag of fertilizer, just like that:

$\#b=\frac{2750}{240}=11.46\cong12$
