Answer:
The area of any regular polygon is given by the formula: Area = (a x p)/2, where a is the length of the apothem and p is the perimeter of the polygon. Plug the values of a and p in the formula and get the area.
Step-by-step explanation:
Answer: 30%
Step-by-step explanation: 60/300 is the same as 30/100 so it is 30%
Answer:
x=lengthNEW-lengthOLD
Step-by-step explanation:
The length of the tree used to be only 1.85m. We call this the old length value of the tree, or in short: "lengthOLD"
Next the tree grew to be 5.30m. We call this the new length value of the tree because this measurement was taken later in time, and so after the first measurment. In short: "lengthNEW" is always the newwest value.
To calculate how much the tree has grown, you need to subtract the two lengths. It alway goes in this way:
The newwest number minus the old number.
In this case: x=lengthNEW-lengthOLD
