Answer:
im not sure but i think its correct (like 80-90%)(but probably not but u can use this method to find the correct answer)
Step-by-step explanation:
a) 25+40= 65 (x) 10= 650/2= 325
b) 325 (x) 50= 16,250cm
c) 325 (x) 2= 650
20 (x) 50= 1000
50 (x) 40= 2000
15 (x) 50= 750
25 (x) 50= 1250
then, just add eveything above should be 5,650cm^2
