1(A) 1.5 length 1.5 width

1(B) 478.5 in meters

2(A) 76.4

Step-by-step explanation:

For the first question, since the land is a square, we would need to find the square root of 2.25 kilometers. That is 1.5, so the answer is 1.5 for both dimensions.

To find the answer to the second question, simply multiply the 2 numbers together and multiply the answer by 1000.

.55*.87= .4785*1000=478.5. The area in meters is 478.5

To calculate the answer to part a of the second question, well have to use the equation pi*diameter=circumference, which well flip around to get diameter=c/pi. Since the circumference is 240, we can divide that by pi to get 76.4 rounded up.

The rest of these questions are kinda out of my league. I hope this helped to the best of  my ability! :D

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
