4 1/5 = (4×5+1)/5 = 21/5
5 1/8 = (5×8+1)/5 = 41/5
So we get 21×41/(5×5) m^2. = 861/25 m^2
1m^2 = 10×10 = 100 dm^2
So the final answer is 861×100/25 = 3444 dm^2
5 1/8 = (5×8+1)/5 = 41/5
So we get 21×41/(5×5) m^2. = 861/25 m^2
1m^2 = 10×10 = 100 dm^2
So the final answer is 861×100/25 = 3444 dm^2

4 1/5m =21/5m
5 1/8m =41/8m
1m =10dm
21/5m = 21/5*10= 42dm
41/8m = 41/8*10= 205/4dm
now, 42dm*205/4dm= 4305/2 sq dm
= 2152.5 sq dm
= 2152 1/2sq dm
5 1/8m =41/8m
1m =10dm
21/5m = 21/5*10= 42dm
41/8m = 41/8*10= 205/4dm
now, 42dm*205/4dm= 4305/2 sq dm
= 2152.5 sq dm
= 2152 1/2sq dm
