Step-by-step explanation:
Given that,
Mr. Hershman has purchased a farm that is in the shape of a rectangle. The dimensions of the piece of land are 4.3 km by 4.85 km. The area of the rectangle is given by :
![A=l* b](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ai9awo8sv0aidmb11ku9ch3s3xstopnnq0.png)
![A=4.3* 4.85](https://img.qammunity.org/2020/formulas/physics/high-school/4e3bg5m1p1d804le0rn8pqrbcodjp9vrti.png)
![A=20.855\ km^2](https://img.qammunity.org/2020/formulas/physics/high-school/p263cy3joupenkyrdea6t89c7z2w25mm9e.png)
So, she must buy
of area.
Since,
![1\ km^2=100\ hectares](https://img.qammunity.org/2020/formulas/physics/high-school/p6fl6nnjkjy77jd5knh30iwsmw4xr0b8ns.png)
So, the area of rectangle is 2085.5 hectares. Hence, this is the required solution.
