Answer:
Area in square kilometers equals ![12.126km^{2}](https://tex.z-dn.net/?f=12.126km%5E%7B2%7D)
Area in hectares equals 1212.6 hectares
Step-by-step explanation:
We know that area of rectangle is length times the breadth.
Using the given values we have
![Area=length\times breadth\\\\\therefore Area =4.7km\times 2.58km\\\\Area=12.126km^{2}](https://tex.z-dn.net/?f=Area%3Dlength%5Ctimes%20breadth%5C%5C%5C%5C%5Ctherefore%20Area%20%3D4.7km%5Ctimes%202.58km%5C%5C%5C%5CArea%3D12.126km%5E%7B2%7D)
Thus he bought land of area ![12.126km^{2}](https://tex.z-dn.net/?f=12.126km%5E%7B2%7D)
We know that 1 hectare =![0.01km^{2}](https://tex.z-dn.net/?f=0.01km%5E%7B2%7D)
Thus 12.126
= 12.126/0.01 hectares
Area in hectares equals 1212.6 hectares
no matter how slanted a rhombus may be, let's recall that all sides in a rhombus are equal, meaning ![3y=15\implies y=\cfrac{15}{3}\implies y=5](https://tex.z-dn.net/?f=3y%3D15%5Cimplies%20y%3D%5Ccfrac%7B15%7D%7B3%7D%5Cimplies%20y%3D5)
