You want to buy additional land in the shape of a rectangle with a width of 2,500 cm and a length of 0.065 km. If the price is Php 150,000/hectare, how much peso do you need to pay?

Correct answer:

x =  24375 P

Step-by-step explanation:

$$\begin{gathered} a=2500\text{cm}\to \text{m}=2500:100\text{m}=25\text{m} \\ b=0.065\text{km}\to \text{m}=0.065\cdot 1000\text{m}=65\text{m} \\ {S}_1=a\cdot b=25\cdot 65=1625{\text{m}}^2 \\ {S}_2=S_1\to \text{ha}=S_1:10000\text{ha}=1625:10000\text{ha}=0.1625\text{ha} \\ x=150000\cdot S_2=150000\cdot 0.1625=24375\text{P} \end{gathered}$$
