Answer:
Width = 65 yards
Length = 120 yards
The other answer is not correct, because it wants you to find another rectangle with the SAME perimeter but SMALLER area. Words are very tricky, especially in math.
Step-by-step explanation:
The rectangular field is 110 yards long and 75 yards wide. The length is 110 yards and the width is 75 yards.
To find the perimeter, just add the four sides, which is:
It wants you to find another rectangle that has the SAME perimeter but SMALLER area (The area of this rectangle is 8250 yards squared.)
There are many answers for this one.
One such answer could be 120 yards long and 65 yards wide, which also:
It also gives 370. This is a rectangle with the SAME perimeter but SMALLER area (the area of this one is 7800 yards squared.)

Answer:
12,345 tablets may be prepared from 1 kg of aspirin.
Step-by-step explanation:
The problem states that low-strength children’s/adult chewable aspirin tablets contains 81 mg of aspirin per tablet. And asks how many tablets may be prepared from 1 kg of aspirin.
Since the problem measures the weight of a tablet in kg, the first step is the conversion of 81mg to kg.
Each kg has 1,000,000mg. So
1kg - 1,000,000mg
xkg - 81mg.
1,000,000x = 81
x = 0.000081kg
Each tablet generally contains 0.000081kg of aspirin. How many such tablets may be prepared from 1 kg of aspirin?
1 tablet - 0.000081kg
x tablets - 1kg
0.000081x = 1
x = 12,345 tablets
12,345 tablets may be prepared from 1 kg of aspirin.
