If the length of a rectangle is doubled and its height quadrupled how is its area changed?
Skylarlouis
Its area is now eight times greater than its original size.
If area = L x H, then 2(L) x (4)H = 8 (original area)

Why is the area of a rectangle base times height?
A rectangle is a good, simple shape to begin with. The area of a rectangle is equal to the product of the length of its base and the length of its height. The height is a segment that is perpendicular to the base. For a rectangle, the base and height are often called the "length" and the "width", and sometimes the height is referred to as the "altitude."
What happens to the volume of a cylinder when the height is double?
The volume is doubled.
What is the new volume of a cylinder if the height and radius are doubled?
If the radius and height of a cylinder are both doubled, then its surface area becomes 4 times what it was originally, and its volume becomes 8 times as much.
The volume of a circular cylinder varies directly with the height of the cylinder and with the square of the cylinder's radius If the height is halved and the radius is doubled then the volume will be?
The volume of a circular cylinder varies directly with the height of the cylinder and with the square of the cylinder's radius If the height is halved and the radius is doubled then the volume will be increased.
How do you find the height of a rectangle with the base and perimeter given?
Height = (Perimeter/2) - Base
If the radius and height of a cylinder are doubled then its lateral are?
quadrupled. :)
How does a volume of a rectangular prism change is the length and width is doubled and the height stays the same?
It is quadrupled.
What is the area of a parallelogram if the base and height are doubled?
As area_of_parallelogram = base x height if they are both doubled then: new_area = (2 x base) x (2 x height) = 4 x (base x height) = 4 x area_of_parallelogram Thus, if the base and height of a parallelogram are [both] doubled, the area is quadrupled.
What happens to the perimeter if the base and height of the rectangle are doubled?
increase
If the base and height of a triangle are doubled how is its area changed?
The area is multiplied by 4, not doubled.
If the base is doubled and the height is halved then how will the new area compare to the old area of a rectangle?
It will be the same.
What happens to the volume of a cylinder if the height is doubled and the diameter of the base is not changed?
since the volume of a right cylinder is height x area of base, the area of the baseis Pi * r^2 (r is radius which is 1/2 of diameter), so the area of the base did notchange, while the height is doubled so the volume is doubled.
What happens to the area of a parallelogram when you double the height and the base?
The area of the parallelogram is quadrupled.
How does the volume of a cylinder change if the height is doubled?
The volume will be doubled.
How does the volume of a cylinder change if the radius is doubled?
It is quadrupled. volume_cylinder = π x radius2 x height If radius → 2 x radius then: new_volume = π x (2 x radius)2 x height = π x 22 x radius2 x height = 4 x π x radius2 x height = 4 x original_volume
What happens to the surface area of a cylinder if the diameter of the base is doubled and the height is not changed?
The base areas quadruple and the curved surface doubles.
What happens to the area of a parallelogram when you double both the height and the base?
The area of the parallelogram is quadrupled.
