Estimate the area of the following figure shown below. each square is 9ft 5.5 ft^2

6ft^2

49.5 ft^2

54 ft^2

  (c)  49.5 ft²

Step-by-step explanation:

We choose to estimate the area by comparison to the figure attached. Its area is (5.25)(9 ft²) = 47.25 ft². We don't believe the discrepancies are so large that we need to add another whole square to the area estimate.

Our choice is 49.5 ft².

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
