ANSWER:

12 bags of fertilizers are needed

Explanation:

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


A=(B_1+B_2)/(2)\cdot h

Replacing:


\begin{gathered} A=(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=(2750)/(240)=11.46\cong12
