Consider that the initial length and width of the rectangle are given as,
After the length is increased by 10%, the new length (L) of the rectangle is calculated as,
After the width is decreased by 10%, the new width (B) of the rectangle is calculated as,
Then the area (A) of the new rectangle is calculated as,
Thus, the new area of the rectangle is 396 square meters.
➷ As there would be 2 circles, you'd need to find the area of a circle and then multiply it by 2
To start with, we can use this:
2 (r^2)
^^ This represents the surface area of the two circles
A cylinder also has a rectangle which is rolled to form the shape
As we know, the formula of a rectangles area is length x width
The width of the rectangle would be equal to the circumference of a circle
circumference of circle =
The length of the rectangle would be the height of the cylinder
We can use this:
This would calculate the surface area as it would find the area of the rectangle plus the area of the two circles.
