Step-by-step explanation:
100% = 100
50% = 100%/2 = 100/2 = 50
100 - 50% = 100 - 50 = 50
100% = 150
10% = 100%/10 = 150/10 = 15
60% = 6×10% = 6×15 = 90
150 - 60% = 150 - 90 = 60
60 is greater than 50.
so, the second one is greater.
Answer:
Area=210
perimeter=66
A=a+b(h)/2
P=a+b+c+d
John is 9 and Olivia is 12
12+18= 20
36+ (9x8)= 108
