which table has the largest area, square tables with a side length of 36 inches, rectangular table 20 inches wide and 73 inches long, round tables with a diameter of 42 inches

The rectangular table has the largest area of 1460 in^2.

Step-by-step explanation:

A table square uses the formula A=s^2  where s is the side length  for it's area.

A rectangle uses the formula A= l*w where l is the length and w is the width for it's  area.

And a circle uses the formula  A = r^2  where r is the radius for its area.

Now use the formulas and solve for the areas

Square:  A= 36^2

          A= 1296  

Rectangle:  73 * 20 = 1460

circle:  42/2 = 21     21 is the radius since half the diameter is the radius

    A= 21^2

   A=441

  A = 1385.44

step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
