Argicultural field

Field has a rectangular shape with a width 180 m and circumference 940 m. How many hectares acreage has field?

Result

x =  5.22 ha

Solution:

a=180 o=940 b=o/2−a=940/2−180=290 S=a⋅ b=180⋅ 290=52200 x=S/1002=52200/1002=26150=5.22 haa=180 \ \\ o=940 \ \\ b=o/2-a=940/2-180=290 \ \\ S=a \cdot \ b=180 \cdot \ 290=52200 \ \\ x=S/100^2=52200/100^2=\dfrac{ 261 }{ 50 }=5.22 \ \text{ha}
