Pavilion

The rectangular pavilion with dimensions 3.5 m and 2.75 m to be paved with square tiles of side 25 cm price of CZK 22 per 1 piece or rectangular tiles with sides of 20 cm and 15 cm in the price of CZK 11 per 1 pc. Which solution is cheaper (write its price)?

Result

x =  3388

Solution:

x=3.52.75/0.25222=3388 y=3.52.75/(0.150.2)11=3529.167 x>y  x=3388 Kc x= 3.5 \cdot 2.75/0.25^{ 2 } \cdot 22 = 3388 \ \\ y= 3.5 \cdot 2.75/(0.15\cdot 0.2) \cdot 11 = 3529.167 \ \\ x > y \ \\ \ \\ x = 3388 \ \text{Kc}
