Answer:
If you mean 4e^x -1=0
4e^×=1
e^x=1/4 , take ln bothside
xlne =ln(1/4)
x=ln(1/4)
The percentage increase in the area of a rectangle is 44% if each of its sides is increased by 20%.
<h3>What is a rectangle?</h3>
It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
New length = (120x/100) m
New breadth = (120y/100) m
New area = (6x/5 × 6y/5) m²
The difference between the original area = xy
new area 36xy/25
Percentage increase = (11xy/25 1/xy x 100)
= 44%
Thus, the percentage increase in the area of a rectangle is 44% if each of its sides is increased by 20%.

<h2>
Hello!</h2>
The answer is:
The total area is:
<h2>
Why?</h2>
To find the cloasest value to the total surface area that will be painted, we need to calculate the area of a single sphere, and then, multiply it by 5.
We know that the diameter of each sphere is 7 centimeters, so, calculating we have:
Calculating the radius we have,
Then, calculating the area, we have:
Now that we have calculated the surface area of a single sphere, we need to calculate the area of the five spheres.
So, calculating we have:
Hence, the total area is:
Have a nice day!
