26²=6.4²+x²
676 = 40.96+x²
x²=635.04
x=25.2
aire = (6.4x25.2)/2 = 80.64m²
rectangle = 25.2x29 = 730.8m²
Il faut retirer :
allée + garage = 5x10.6 = 53m²
maison : 7.1x11.3 = 80.23m²
terrasse ; PixR²/2 = 19.78m²
A tondre
80.64+730.8-53-80.23-19.78 = 658.43m²
Haie : 26+6.4+29+25.2-5 = 81.6m à tailler
100m² = 10 min
658.53m² = x
x=65.84 min
60min = 30 €
65.84 min = x
x = 32.92€
30 min = 7m
x= 81.6
x = 349.71 min
30€ = 60 min
x = 349.71 min
x = 174.85
total 174.85 + 32.92 = 207.77 €
