Wheat

A rectangular field with dimensions 529 m × 1001 m yielded 2780 quintals of wheat last year (1 quintal = 100 kg). During the year, a pipe had to be repaired, which meant that a strip 4 m wide parallel to the side of length 1001 m could not be used for growing crops. By what percentage can the harvest be expected to decrease in the following year?

Final Answer:

p =  0.7561 %

Step-by-step explanation:

$$\begin{gathered} a=529\text{m} \\ b=1001\text{m} \\ c=4\text{m} \\ p=100\cdot \frac{c\cdot b}{a\cdot b} \\ p=100\cdot \frac{c}{a}=100\cdot \frac{4}{529}=\frac{100\cdot 4}{529}=\frac{400}{529}=0.7561\% \end{gathered}$$
