1. 4 rajoles
20 m2
x 4 rajoles/m2
= 80 rajoles
20 m2
x 18 €/m2
= 360 Euros
360 € x 15/100 = 54 € descompte 360 € - 54 € = 306 € Preu Final

2. Area (m2
) = costat (m) x costat (m)
6000 m2
= 100 m x ¿? (m)
6000 m2 : 100 m = 60 m
Ojo
R: les dimensions del camp son 100 m x 60 m
100 m x 12 €/m = 1200 €
(60 m + 60 m +100 m) x 7 €/m = 1540 €
1200 € + 1540 € = 2740 €
2740 € x 16/100 = 438.40 €
Total= 2740 + 438.40 = 3178,40 €
