Bonjour,
1) tu calcules BC avec pythagore
BC² = BD²+DC²
calcule BD
2) P terrain = AB+BC+CE+EA
calcule, tu as les mesures
prix : 25,9e le rouleau de 20m,
calcule combien il faut de rouleaux : P/20 = ....
1 rouleau coute 25,90e , tu calcules le prix des rouleaux
3) A rectangle = 20*40 = 800m²
A triangle = 40*30/2 = 600m²
A totale = 1400m²
un sac de gazon couvre 500m²,
il lui faut 1400/500 = 2,8 soit 3sacs
calcule le prix des sacs
dépense totale : prix grillage + prix sacs
