Floor

The floor area of ​​the room is 31 m2 and has a width of 4.3 m. How many centimeters of circumference measured floor on the map at the scale 1:75?

Result

o =  30.7 cm

Solution:

o=2(a+b)10075=2(a+Sa)10075= o=(4.3+314.3)20075=30.7 cmo = 2(a+b)\cdot \dfrac{100}{ 75} = 2(a + \dfrac{ S}{a}) \cdot \dfrac{100}{ 75} = \ \\ o = ( 4.3 + \dfrac{ 31}{ 4.3}) \cdot \dfrac{200}{ 75} = 30.7 \ \text{cm}
