Answer:
132.4m^2
a) 1/8(1/6)= 1/48
b) 1/2(1/8)= 1/16
c) 1/4(1/3)= 1/12
A) 2/45
B) 1/45
C) 1/30
D) 1/15
E) 2/15
F) 4/45
Explanation:
1) 6.2m(12m)= 74.4m^2
10m(5.8m)= 58m^2
74.4m^2 +58m^2= 132.4m^2
2)
a) 1/8(1/6)= 1/48
b) 1/2(1/8)= 1/16
c) 1/4(1/3)= 1/12
3)
a) 4/10(1/9)= 4/90= 2/45
b) 2/10(1/9)= 2/90= 1/45
c) 3/10(1/9)= 3/90= 1/30
d) 3/10(2/9)= 6/90= 2/30= 1/15
e) 4/10(3/9)= 12/90= 4/30= 2/15
f) 2/10(4/9)= 8/90= 4/45
