There an old algorythmic method similar to long division:-
7 . 4 8 3
-----------------
) 56. 00 00 00
7 ) 49
) ---
144 ) 7 00
) 576
----
148 8 ) 12400
) 11904
-------
) 496 00
1496 3 ) 44889
THis gives the square root as 7.48 to the nearest hundredth
20/29
16/34
40/41
21/20
30/40
21/29
Area = 35/4 m²
Length = 7/2 m
Area = length * width
35/4 = 7/2 * width
7/2 * width = 35/4
width = 35/4 ÷ 7/2
width = 35/4 × 2/7 = 5/2
Width = 5/2 m
The answer is c, or .236. If you enter 0.4 times 0.59, you end up with 0.236.
