Width is 3/8 meter and area is 9/10 square meter
what is the length of tile designing

  2 2/5 m

Step-by-step explanation:

Area is the product of length and width. Fill in the given information and solve for length:

  A = LW

  9/10 m² = L(3/8 m)

  L = (9/10 m²)/(3/8 m) = (9/10)(8/3) m = 12/5 m

  L = 2 2/5 m

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)
