What is the length and width of a rectangle with a perimeter of 135 and a scale factor of 8 to 1?

Let w equal the width and l equal the length of the rectangle. This means that 2w+2l=135 and since the rectangle has a scale factor of 8:1, that w/l=8. We now have a system of equations. Solve the second equation for w and find that w=8l. Substitute this into the first equation and find that 2(8l)+2l=135, which simplifies to 18l=135. Solve for l to get l=7.5 units. Plug this into either of the original equations to find that w=60 units. The dimensions of the rectangle are 60 by 7.5 units.

Rectangle A is width 4 and length 8 so draw similar rectangle scale factor 2.5?
Draw a 10 x 20 rectangle.
What is the scale factor of 0.8?
When two similar shapes have a scale factor of 0.8, every length of the second is 0.8 times the corresponding length of the first.
How do you find the scale factor of a cylinder?
how to do a scale factor of cylinder is that you find the base and the height and the length of A area hope you like my examples.
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.
How do you find a scale factor of a triangle?
To find the scale factor of two triangles, look first for one pair of corresponding sides--one side from the smaller triangle and the corresponding side from the larger triangle. Divide the larger side length by the smaller side length, and that quotient is your scale factor.
What is the perimeter of a rectangle 7 in by 2 in enlarged by the scale factor of 1.5?
A rectangle 10.5 x 3 will have a perimeter of 27 in.
How do you enlarge a rectangle by 2.5 with scale factor?
If you assume that 2.5 refers to the scale factor, you multiply each linear measurement by 2.5. This includes the width, the length, and - if you want to use it to construct your new rectangle - the diagonals. It also happens to include the perimeter, but you probably won't need that to construct the rectangle.
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
The scale factor of a rectangle is 1 the length of the short side of the rectangle is 1 what is the length of the long side of the rectangle?
It is 5!!!! It can be any number
How does scale factor relate to perimeter?
Scale factor and perimeter are related because if the scale factor is 2, then the perimeter will be doubled. So whatever the scale factor is, that is how many times the perimeter will be enlarged.
What happens to the perimeter when a rectangle is enlarged by a scale factor of 3?
It will be three times the size. Each length will be multiplied by 3.. Perimeter = h+h+w+w if we multiply each by three then we get 3h+3H+3w+3w = 3P
Rectangle A is width 4 and length 8 so draw similar rectangle scale factor 2.5?
Draw a 10 x 20 rectangle.
What does the scale factor between two similar figures tell you about the perimeter?
The perimeter will scale by the same factor.
How can you use scale factor to find a new perimeter and area?
New perimeter = old perimeter*scale factor New area = Old area*scale factor2
What do you get when you enlarge a rectangle with a 1cm side and a 3cm bottom by sf2?
When enlarging each length is multiplied by the scale factor, so with a scale factor of 2 each length is multiplied by 2, to give a new rectangle 1cm x 2 = 2cm by 2 x 3cm = 6cm.
What is the scale factor of two figures with a perimeter of 50 Cm and 75 Cm?
There need not be any. There is no scale factor between a pentagon with a perimeter of 50 cm and a triangle with a perimeter of 75 cm. The shapes are totally different!The scale factor is 2 : 3.
Perimeter ratio 100 and find scale factor?
The linear scale factor is 100.
