Answer:
16√3 cm²
Step-by-step explanation:
The perimeter of a triangle is the sum of its all three sides. Since this is an equilateral triangle, all sides are equal.
Let's consider one side of the triangle to be 'x'
Givent that, the perimeter is 24cm,
The equation should be x + x + x = 24
⇒3x = 24
∴ x = 8 cm
To find the area of the triangle, we need to find the height, and for that, we can use trigonometry.
Since it is an equilateral triangle, all angles are exact 60°.
let's draw a line and mark it as 'h'.
we can use sine formula to find out the opposite i.e. h
sin∅ = opposite ÷ hypotaneous
sin 60° = h ÷ 8
h = 8 sin 60°
h= 4√3
Now, let's find the area
Area = 1/2 × base × height
Area = 1/2 × 8 × 4√3
area= 16√3 cm²
Answer:
The doctor's dosage was not appropriate.
The right dosage is from 56.625 mg to 113.25 mg of Antibiotic to be given every 6 hour for the child with weight 25 lbs.
Step-by-step explanation:
It is given that 20 to 40 mg/kg/day is the recommended dosage.
Now, the doctor's order is 150 mg of antibiotic to be given every 6 hours. And my child weighs 25 lbs.
Now, 1 lb is equivalent to 0.453 kg.
So, my child's weight is (25 × 0.453) = 11.325 kg.
So, the doctor's order is 150 mg of antibiotic to be given every 6 hours for a child of weight 11.325 kg.
Hence, the dosage is [(150 × 4) ÷ 11.325] = 52.98 mg/kg/day.
So, this is not within the limit of 20 to 40 mg/kg/day.
Therefore, the doctor's dosage was not appropriate.
Now, let the appropriate dosage is x mg per every 6 hours for a child with weight 25 lbs i.e. 11.325 kg.
So,

So, the right dosage is from 56.625 mg to 113.25 mg of antibiotic to be given every 6 hours for the child with weight 25 lbs. (Answer)
