Finding Length and Width When You Know Area and Perimeter If you happen to know the distance around the rectangle, which is its perimeter, you can solve a pair of equations for L and W. The first equation is that for area, A = L ⋅ W, and the second is that for perimeter, P = 2L + 2W.

Area is measured in square units. The area of the rectangle can be calculated using the following formula: A = l   w, where l represents the length and w represents the width. Perimeter is the length of the boundary of the shape. It can be calculated adding the measurements of each side.

The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the amount of surface the shape covers. You measure area in square units of a fixed size.

The perimeter of a rectangle (the distance around it) can be found either by finding the sum of the lengths of the sides or by using the formula P = 2l + 2w. Since perimeter is a length or distance, the unit of measure is inches, feet, yards, or miles. The area of the rectangle is found by using the formula A = l × w.

Explanation: To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides.

Width. Divide the area by the length if you are given these two figures but not the width. For example, if a rectangle has an area of 20 square feet and a length of 10 feet, divide 20 by 10 to get a width of 2 feet. Multiply the length times 2 and subtract this figure from the perimeter, if you're given these values.

The perimeter P of a rectangle is given by the formula, P=2l+2w , where l is the length and w is the width of the rectangle. The area A of a rectangle is given by the formula, A=lw , where l is the length and w is the width.

To find the area of a rectangle, you need two measurements: the width, or base (the longer side of the rectangle), and the length, or height (the shorter side of the rectangle). Then, just multiply them together to get the area. In other words: Area = base × height, or A = b × h for short.

Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle). That is, the area of the rectangle is the length multiplied by the width. As a special case, as l = w in the case of a square, the area of a square with side length s is given by the formula: A = s2 (square).

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The perimeter, P, is: P=x+x+y+y.

Explanation: Divide the area of the rectangle by the width in order to find the length of 14 feet. The perimeter is the sum of the side lengths, which in this case is 14 feet + 4 feet +14 feet + 4 feet, or 36 feet.

The perimeter is found by adding the lengths of all 4 sides. Since your quadrilateral is on a graph, I assume you know the end points of each side? If the sides are all horizontal or vertical, then the lengths would be simply the difference between the x or y points (x for horizontal sides, y for vertical sides).

To find the perimeter, add every side of the shape to find the total. If one or more sides are fractions, you will have to follow the rules for adding fractions to add each side and find the perimeter.

Perimeter of triangle = a + b + c where a, b and c are the three lengths of the triangle. This would be the perimeter of a rectangular prism formula: Perimeter of rectangle: 2l + 2w where l is the length of the rectangle and w is the width.
