30 m * 1,5 = 45 m
30 m * 2 + 45 m * 2 = 60 m + 90 = 150 m
150 m - 2 m - 1 m = 147 m
ODPOWIEDŹ.:Potrzeba 147 m siatki.
Dasz naj..? pliss xDD
b=1,5x30=45
O=2a+2b
O=30x2+45x2
O=60+90
O=150[m]
150-(2+1)=150-3=147[m]
obwód prostokąta 2a+ 2b
x =a +b
(30m + 1,5 * 30m) - (2m + 1m)= x
(30m + 45 m) - 3m =x
75 m - 3m=x
72m =x
2x= 2 * 72m
2x =144m
