Odpowiedź :
a)
64 : 4 = 16
a = 16
P = a*a
P = 16*16 = 256 cm ²
b)√64 = 8
a = 8
Ob = 4a
Ob = 4 * 8
Ob = 32 cm
64 : 4 = 16
a = 16
P = a*a
P = 16*16 = 256 cm ²
b)√64 = 8
a = 8
Ob = 4a
Ob = 4 * 8
Ob = 32 cm
a)
O=64cm
O=4a
64=4a/:4
a=16cm
P=16cm²
P=256cm2
b)
P=64
P=a²
64=a²/√
a=8
O=4*8=32
O=64cm
O=4a
64=4a/:4
a=16cm
P=16cm²
P=256cm2
b)
P=64
P=a²
64=a²/√
a=8
O=4*8=32
