a, b - boki prostokąta
d - przekatna prostokąta
2a + 2b = 62
b = a-17
2a + 2(a-17) = 62
2a + 2a -34 = 62
4a = 96
a = 24
b = 24-17=7
[tex]a^{2} + b^{2} = d^{2} \\ {24}^{2} + {7}^{2} = {d}^{2} \\ 576 + 49 = {d}^{2} \\ d = \sqrt{625} = 25[/tex]
25 - 2 = 23 (tyle sadzonek na przekatna )
23*2 = 46
Trzeba zakupić 46 hortensji
