Răspuns:

Explicație pas cu pas:

363+a+242=726

a+605=726

a=726-605

a=121

(21+51):9*(153-b)=96

72:9*(153-b)=96

8*(153-b)=96

153-b=96:8

153-b=12

b=153-12

b=141

(c:4+78):10+65=75

(c:4+78):10=75-65

(c:4+78):10=10

c:4+78=10*10

c:4+78=100

c:4=100-78

c:4=22

c=22*4

c=88

Sp=P/2=(141+121+88)/2=(262+88)/2=350/2=175
