Answer:
1.05 m
Step-by-step explanation:
The area of a rectangle is length x width
The area is given as 18,900 cm2 and the width is 1.8 m
These need to be in the same unit, either cm or m
1 m = 100 cm
change the 1.8 m width to cm by multiplying by 100
1.8 x 100 = 180 cm
plug in 180 for the width
again, area = L x W
so 18,900 = L x180
L = 105 cm
The question asked for the length in meters so convert back
105 cm ÷ 100 = 1.05 meters
Answer: 1.05 meters
An arithmetic sequence is a sequence where the difference d between successive terms is constant. The general term of an arithmetic sequence can be written in terms of its first term a1, common difference d, and index n as follows: an=a1+(n−1)d.
The area of forest after 5 years is 2846.93 square kilometer
<em><u>Solution:</u></em>
Given that, A certain forest covers an area of 4500 square kilometer
Suppose that each year this area decreases by 8.75%
To find: Area after 5 years
<em><u>The decrease function is given as:</u></em>
Where,
y is the value after t years
A = initial amount
r = decreasing rate in decimal
t is the number of years
Here in this sum,
A = 4500
t = 5 years
<em><u>Substituting the values in formula,
</u></em>
Thus the area of forest after 5 years is 2846.93 square kilometer
