Odpowiedź :
a - bok kwadratu
a√2=1,6m
a=1,6m/√2
(1,6/√2)² = 2,56/2 = 1,28
Odp. P = 1,28m²
a√2=1,6m
a=1,6m/√2
(1,6/√2)² = 2,56/2 = 1,28
Odp. P = 1,28m²
d=a√2
d=1,6 m =160 cm
160=a√2
a=(160√2)/2=80√2
P=a²
P=(80√2)²=12800 cm²=1,28m²
d=1,6 m =160 cm
160=a√2
a=(160√2)/2=80√2
P=a²
P=(80√2)²=12800 cm²=1,28m²
