Answer:
W ≈ 5.2 cm
Step-by-step explanation:
Represent the length and width by L and W respectively.
Then L * W = 81 cm^2, and L = 3W.
Substituting 3W for L in the first equation, we get:
3W * W - 81 = 0, or 3W^2 - 81 = 0.
To make it easier to find the final answer, rewrite 3W^2 - 81 = 0 as
81
W^2 = ------- = 27
3
Then W (the width) is the positive square root of 27, or W ≈ 5.2 cm

Rounded to the nearest thousandth
3n = 3 (0.333) = 0.999 = 1
-n/3 = -0.333/ 3 = -0.111
2n = 2(0.333) = 0.666 = 0.667
I think it's 10 times bigger than 756 because in 37,856 the 7 is in the thousands place and in 756 the 7 is in the hundreds place
