What are the dimensions if the perimeter is 124 feet and the length is 6 feet more than 3 times the width?
Create an equation to solve the problem.
p=2l=2w
l=3w+6
the perimeter is 124. We substitute 124 for p and 3w+6 for l to reach the following solvable equation
124=2(3w+6)+2w
124=6w+12+2w (distribute the 2 over 3w+6)
124=8w+12 (combine like terms)
124-12=8w+12-12 (subtract 12 from both sides to isolate the variable w)
112=8w (combine like terms again)
112/8=8w/8 (divide both sides by 8 to isolate w)
14=w
We now know the width is 14 feet. We then substitute that value for w in the equation we wrote for the value of l
l=3w+6
l=3*14+6
l=42+6
l=48
The length is 48 feet. We can now substitute both values into the equation for perimeter to check our answer.
p=2w+2l
124=(2*14)+(2*48)
124=28+96
124=124
The result is true, so the result is correct.

What are the dimensions of a table if the perimeter is 36 and the length is 5 times the width?
perimeter = length + length + width + width = 2*length + 2*width = 36 length = 5*width 2*(5*width) + 2*width = 36 12*width = 36 width = 3 length = 15
What is an expression for the perimeter of a rectangle that has a length which is seven times its width?
Perimeter = length + length + width + width Let "w" = width, then "7w" must equal the length (because it's 7 times the width) 7w + 7w + w + w = perimeter 16w = perimeter

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.
What are the dimensions of a table if the perimeter is 36 and the length is 5 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 can be concluded about a rectangles width if the ratio of length to perimeter is 1 to 3?

When people say perimeter is the length times width do they mean the whole shape?
If people say that "perimeter is the length times width" stop listening to them. They don't know what they are talking about.Length times width is the area, not the perimeter. For a square or rectangle, the perimeter is double the sum of the length and the width.
What is the effect on the perimeter of a rectangle if the dimension are doubled what is the effect on its perimeter?
A rectangle has two dimensions - length and width. Only if both dimensions are doubled, then the perimeter will be doubled.

The length of a rectangular hallway is three times the width the perimeter is 72ft find the dimensions of the hallway?
Length is 3/4 of 36 ie 27 ft, width is 9 ft
What is an expression for the perimeter of a rectangle that has a length which is three times its width?
call width x so length is 3x perimeter is (2*length)+(2*width) so perimeter is 8x
