What happens to the perimeter when a rectangle is enlarged by a scale factor of 5?
if the length and breadth are increased by 5 times each area becomes 25 times
What happens to the area of a rectangle if you half the width?
It becomes half of what the original area is.
How do you find the length and breadth if area is known for a rectangle?
If you do not know the length or breadth of a rectangle, you cannot know the area. If you do not know the area of a rectangle, you cannot know the length and breadth. To know the length and breadth of a rectangle, you have to know some other contributing factor in the equation. If you don't, measure it!
What happens to the area of a rectangle if one side is doubled?
Area = length*width new Area = 2 * length * width Area is doubled
What happens to the perimeter and the area of a rectangle if you double the length and the width?
the perimeter will double. but the area should doubled to four
What happens to the perimeter when a rectangle is enlarged by a scale factor of 5?
if the length and breadth are increased by 5 times each area becomes 25 times
Rectangle with area of 144 and scale factor of 4 what is the area of a similar rectangle?
576
Suppose rectangle E has an area of 9 square centimeters and rectangle F had an area of 900 square centimeters The two rectangles are similar What is the scale factor from rectangle E to rectangle F?
100 is the scale factor
How are factors related to area?
Some people relate factor pairs to the sides of a rectangle. Length times width equals area; factor times factor equals product.
What happens to the area of a rectangle if the width doubles?
The area also doubles.
What happens to the area of a figure when the scale of the figure changes?
To find the new area, you have to multiply the original area by the square of the scale change. For example, you have a rectangle with adjacent sides of 3 and 4. Another rectangle has the same dimensions but with triple the scale. The original rectangle's area is 12. Multiply that by 9, which is the square of the new scale, and you get an area of 108. That matches up with the area of the new rectangle, which has adjacent sides of 12 and 9.
A factor pair for a rectangle with an area of 100 and a perimeter of 50?
(20,5)
What happens to the area of a rectangle if you half the width?
It becomes half of what the original area is.
What happens to the area of a rectangle if you halve each side?
1/4th of intial area
What happens to the area of a rectangle if both the length and width double?
the area also doubles
What happens to the area of a rectangle if the length decreases by one-half?
The area is directly proportional to both the length andwidth of a rectangle. Thus if one is halved then the area is also halved.
How do you find the length and breadth if area is known for a rectangle?
If you do not know the length or breadth of a rectangle, you cannot know the area. If you do not know the area of a rectangle, you cannot know the length and breadth. To know the length and breadth of a rectangle, you have to know some other contributing factor in the equation. If you don't, measure it!
