Presumably 300 is the perimeter if so then let length be x and the width be 20x:
2(length+width) = perimeter
2(x+20x) = 300
2x+40x = 300
42x = 300
x = about 7.142857143 units
20x = about 142.857429 units

Does length times width measure the perimetre?
length plus width equals perimetre
What equation would you use to find the volume of a rectangular a.volume equals lengthwidthheight b.volume equals length plus width plus height c.volume equals lengthwidth d.volume equals length plus?
The equation to find the volume of a rectangular object is (a) volume equals length times width times height.
Formula for length of a rectangle?
a = L x W: area equals length times the width. p = 2L + 2W: perimeter equals 2 times the length plus 2 times the width so L = (p - 2W)/2
When given the perimeter how do you find the length and width?
Assuming you mean a rectangle: use the formula:p = 2(l+w) (i.e., perimeter equals twice length plus width). In this formula, replace p with the known perimeter, and l with the given length, then solve for width.
What can be concluded about a rectangles width if the ratio of length to perimeter is 1 to 3?
The width is half the length: The perimeter is twice the length plus twice the width. If the perimeter is 3 times the length, twice the width must be the length.
Does length times width measure the perimetre?
length plus width equals perimetre
What does length plus length plus width plus width equals?
it equals LxL+WxW

What is length plus width?
2 times length plus 2 times width = perimeterhalf the perimeter of a rectangle
What is the perimeter of a rectangle with width 3n plus 2 and length n-1?
perimeter equals 2 times width plus 2 times length so, perimeter equals 2(3n+2)+2(n-1) = 6n+6+2n-2 = 8n+4.
A rectangle has a perimeter of 40 the lenght is 4 times the width what are the dimenisons of the rectangle?
The length is 16 and the width is 4. 2x16 plus 2x4 equals 40.
Show a rectangle that has permeter and area?
The area is the length times the width. The perimeter is two times the length plus two times the width.
What is the area and perimeter of a shaded rectangle?
The area is the length times the width. The perimeter is two times the length plus two times the width.
What is the permeter and area ofthe shaded rectangle?
The area is the length times the width. The perimeter is two times the length plus two times the width.
