Since every rectangle has four sides, if you know the perimeter, divide it by four to find the length of each side. Then find the area by multiplying the length times the width. If you know the area and want to find the minimum perimeter possible, take the square root of the area to find the length of each side.

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 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.

Here is the complete answer. Length = distance between (1,3) and (3,1) = √[(3-1)^2 + (1-3)^2)] = √8 = 2√2. So the area of the rectangle is 4√2 • 2√2 = 16.

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.

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. Apply standard perimeter calculations to the base shape of the prism, and that gives you the perimeter.

Answer: It's perimeter = 2 × (length + breadth ). Because the door is a rectangle .

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.

Perimeter of a rectangle. The perimeter of a rectangle is the total length of all the sides of the rectangle. Hence, we can find the perimeter by adding all four sides of a rectangle. Perimeter of the given rectangle is a + b + a + b.

Multiply the length of one side of a regular polygon by the number of sides to find its perimeter. Regular polygons have identically sized sides. For example, if the shape is a regular pentagon, which has 5 sides, with a side length of 4 inches, then multiplying 4 inches by 5 results in a perimeter of 20 inches.

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 is the sum of all sides of a figure to get one length. So, to find the perimeter, the formula is base + height + base + height. If the base is 10 inches and the height is 5 inches, you would have: Perimeter: 10 + 5 + 10 + 5 = 30 inches.

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.
