If the rectangle has a width of x inches, and a length of x + 16 inches, then its perimeter equals to 2x + 2x + 32 or 4x + 32.
If x = 14, then x + 16 = 30. So the perimeter of rectangle becomes 2(14) + 2(30) = 28 + 60 = 88 inches.

How do you find an expression for the perimeter of a shape?
depending on what your shape is labled as, you add all the expressions up around the outside edge. and sides that are the same have the same expression. so, if it is a square or rectange, the sides opposite each other are the same. after putting all of these expressions together, you can then simplify the expression to give you your final answer. eg. a rectangle with sides 'x+2' and 'x'. you know that the oposite sides of the rectangle are the same so now you have all the sides so: x + x + x+ 2 + x + 2 (simplify) 4x + 4 this is your final perimeter for your rectangle as an expression =P (other shapes with more than 4 sides can still be done as long as you can find lengths that are the sema side and then add them all together still)
What is the perimeter of a square tile with sides 12 inches long?
To find the perimeter of any polygon just add the length of everyside. In this case you have 4 sides with a length of 12 in. so 12 + 12 + 12 + 12 = perimeter. or to simplify 4 * 12 = perimeter.
How big is a 12 by 12 room?
To solve for area: A=lw (Area equals length times width) The length and width are both 12. Substitute 12 for l and w. A=12x12 Multiply. A=144 The room has an area of 144 units. To solve for perimeter: P=2l+2w (Perimeter equals two time the length plus two times the width). Substitute 12 for l and w. P=(2x12)+(2x12) Simplify. P=24+24 P=48 The room has a perimeter of 48 units.

How do you simplify an expression for the perimeter and area of a rectangle?
Represent the length of the rectangle by L and the width by W. The perimeter = 2L + 2W = 2(L + W). The area = L x W.
The width of a rectangle is X plus 4Cm its length is X plus 7Cm greater than its width represent its perimeter and simplify?
width = (x + 4) cm length = [(x + 4) + (x + 7)] cm Rectangle Perimeter = 2[(x + 4) + (x + 4 + x + 7)] cm Rectangle Perimeter = 2[(x + x + x) + (4 + 4 + 7)] cm Rectangle Perimeter = 2(3x + 15) cm Rectangle Perimeter = (6x + 30) cm
What is the perimeter of the quadrilateral?
The perimeter of a quadrilateral is 'side + side + side + side = perimeter'. If the quadrilateral is a square, you can simplify this to 'side x 4 = perimeter'.
How do i write an expression for the perimeter?
To calculate the perimeter, by definition, you must add up all the sides. The details, of course, vary from case to case. For example, if you have an arbitrary triangle, the expression would be something like side1 + side2 + side3 (or whatever the sides are called). In some cases you can simplify the resulting expression; in an isosceles triangle, you have two equal sides, so you get an expression similar to a + a + b = 2a + b. In a rectangle, opposite sides are equal, so you get perimeter = a + b + a + b = 2a + 2b or 2 (a + b).

How do you add and subtract algebraic expressions for example My homework says which expression represents the perimeter in units of this trapezoid?
To add and subtract algebraic expressions the simple rule of like terms applies. In your homework that asks for the expression represents the perimeter in units of this trapezoid you will need to find the like terms and simplify.
the width of a rectangle is w centimeters. the length of this rectangle is three times its width. the perimeter of the rectangle is greater than 64 centimeters. give the inequality that represents all possible values of w?
Let's set up an inequality to represent all possible values of the width (w) of the rectangle given the information provided. The length of the rectangle is three times its width, so the length (L) can be expressed as L = 3w. The perimeter (P) of a rectangle is given by the formula: P = 2(L + w). The perimeter is greater than 64 centimeters, so we have P > 64. Now, substitute the expression for L from step 1 into the perimeter formula from step 2: P = 2(3w + w) Simplify the expression inside the parentheses: P = 2(4w) P = 8w Now, we have the perimeter in terms of the width: P = 8w. We already know that P > 64, so we can write the inequality: 8w > 64 To isolate w, divide both sides of the inequality by 8: w > 64 / 8 w > 8 So, the inequality representing all possible values of the width (w) is: w > 8 This means that the width of the rectangle must be greater than 8 centimeters for the perimeter to be greater than 64 centimeters.
What is the perimeter of a square tile with sides 12 inches long?
To find the perimeter of any polygon just add the length of everyside. In this case you have 4 sides with a length of 12 in. so 12 + 12 + 12 + 12 = perimeter. or to simplify 4 * 12 = perimeter.
What does write an expression for the perimeter mean?
Basically, the perimeter of a shape is the total legnth of all it's sides, therefore to write an expression for it, you need to get the legnths of the sides (even if there is a letter (eg: n)), then put them into an expression. For instance: A polygon has 2 sides that are 15cm long, 1 side that is 22cm long, 4 sides that are n long and 3 sides that are a long. To write the expression for the perimeter of this polygon as basically as possible, you would write: 15cm + 15cm + 22cm + n + n + n + n + a + a + a Now you need to simplify it: 52cm + 4n + 3a If you were asked this question, you would write 52cm + 4n + 3a as your answer. That is an expression for the perimeter of that particular polygon. If you apply the same theory to any question like the one you asked about, you would get it right.
Find the width of a rectangle with a length of 6 yd and a perimeter of 18 yd.?
The formula for perimeter is 2L+2W=P so 2*6+2*W=18 simplify 12+(2*W)=18 subtract across 2*W=6 i take it you can get it from here 3 for those of you who can't divide
How do you find the perimeter of a rectangle if the area and base is given?
Well, the area of a rectangle is "base*height"You need to find the height in order to find the perimeterYou need to substitute everything you need to know in the area formulaEx: base=5 area=205*h=20Now you need to simplify the problemEx: h=4So now we know that the height is 4The perimeter formula is (2*base)+(2*height)Ex: (2*5)+(2*4)10+8Perimeter = 18
The length of a rectangle is 3 times the width and the perimeter is 22 Find the dimensions of the rectangle?
The width is 22/8 or 11/4 or 2.75. The length is 66/8 or 33/4 or 8.25. Length = 3W 3W + 3W + W + W = 8W 8W = 22 W = 22/8 L = 66/8 Then, you can simplify as you choose.
