The perimeter is all the sides added together so it would Be 3+3+7+7 the perimeter is 20

How can you calculate the length of a rectangle if the perimeter and the width are given?
Because the perimeter is lenght + length +width +width, you do perimeter - double the width, and then halve the remaining number. that should give you the length.
What is the perimeter of a retangle with the length of 45 cm and width of 30 cm?
we know,perimeter of rectangle = 2 * ( l+b) perimeter= 2 *(45+30) = 2 * 75 =150 cm
How do you find the area of a retangle?
Length X Width
The width of a retangle is fixed at 16cm what lenghts will make the perimeter greater than 78cm?
The perimeter of a rectangle is 2 x length + 2 x width. If the width is 16 then 78 = 2 x length + 2 x 16 2 x length = 78 - 32 = 46 length = 23. For the perimeter to be greater than 78 cm, the length must be greater than 23 cm
How do you find the width of a retangle if the perimeter is 347 feet?
W = (347/2) - L, so you need the length, or the area, but that involves a more complex calculation...
The width of a retangle is fixed 30 cm what lengths will make the perimeter greater than 78 cm?
Any length greater than 9 cm.
Area of a retangle?
The area of a rectangle is length x width.
How can you get the width when you have the perimeter and the length?
If the shape is a rectangle, then Perimeter = 2(Length + Width) So Width = Perimeter/2 - Length
If the perimeter is 48 If the length is twic the width what is the length of rectangle?
perimeter = (2*length) + (2*width) length = 2*width so perimeter = (2*2*width) + 2*width = 6*width perimeter = 48 so you can figure out the width and length
How do you find the length of a rectangle if the perimeter is 40 and the width is 2inches?
perimeter = 2 x (length + width) ⇒ length + width = perimeter ÷ 2 ⇒ length = (perimeter ÷ 2) - width So to find the length of the given rectangle, subtract the width from half the perimeter is how to do it. IF you meant "What is the length..." then: length = perimeter ÷ 2 - width = 40 ÷ 2 - 2 in = 20 - 2 in = 18 in
What is one different way to to find the perimeter of a rectangle?
Length + length + width + width = perimeter. Length + width x 2 = perimeter
How do you find semiperimeter of a retangle?
Add the length and width of the rectangle. That would do it.
