It is: 12 units in length
Multiply the long side of the rectangle's length by itself.
The area of a rectangle is the long side length multiplied by the short side length. In this case 10m x 4.5m = 45 square metres
-- Slice it down one side and flatten it out. -- Now you have a rectangle. You only have to find the area of a rectangle. -- The area of a rectangle is (length) times (width). -- The length of the rectangle used to be the length of the cylinder. -- The width of the rectangle used to be the circumference of the cylinder's round ends, while it was still rolled up.
The size or length of a square is related to its area as the area of a rectangle s the product of the length times the width. As a square is a special type of rectangle, where the length is equal ti the width, the area of a square is the length times the length or length^2, also spoken as "length squared".
Length of a long side x length of a short side = area
If the perimiter is 20 and one side is [[length]] then the other side is (10 - [[length]]). So the area is: [[length]] x (10 - [[length]]) square metres.
you divide the area by the length and you have the other side
It is: 12 units in length
It is the same as for a rectangle, the length of the shorter side x the length of the longer side
You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.
Multiply the long side of the rectangle's length by itself.
If you know the length of one side - and the area... divide the area by the known side - to get the value of the unknown.
The area of a rectangle is the long side length multiplied by the short side length. In this case 10m x 4.5m = 45 square metres
The rectangle.
Area = length*width new Area = 2 * length * width Area is doubled
-- Slice it down one side and flatten it out. -- Now you have a rectangle. You only have to find the area of a rectangle. -- The area of a rectangle is (length) times (width). -- The length of the rectangle used to be the length of the cylinder. -- The width of the rectangle used to be the circumference of the cylinder's round ends, while it was still rolled up.
