Add together the lengths of each of its sides.

To find the perimeter of a polygon, just add the length of all the sides. In this case, the four sides of the rectangle.

X+y^2+2y=-1

Perimeter is the sum of all of the sides, so perimeter can be written as P=2x + 2y First you need to plug in the values you know 360 = 2(84) + 2y Multiply 360=168 + 2y Subtract 192=2y and divide y=96 feet so the length is 96 feet

The question doesn't nail it down; i.e., there can be several answers that satisfy the given information. Perimeter 'P' = 2 x (Length + Width) Area 'A' = (Length) x (Width) = 2 x y What is the Length, and what is the Width ? Here are five correct answers: ==> If the rectangle is (2) by (x y), A = 2xy, P = 4 + 2xy ==> If the rectangle is (2x) by (y), A = 2xy, P = 4x + 2y ==> If the rectangle is (x) by (2y), A = 2xy, P = 2x + 4y ==> If the rectangle is (1) by (2xy), A = 2xy, P = 2 + 4xy ==> If the rectangle is (0.1) by (20xy), A = 2xy, P = 0.2 + 40xy

Let x be the length and y be the width.x=2yPerimeter = 2 x length + 2 x width = 2x+2y = 2(2y)+2y = 4y+2y=6y6y = 60y=10width is 10Length is 2y = 20Area = length x width = 20 x 10 = 200 square feet

let x=length of rectangle let y=width of rectangle x=y+5 2x+2y=40 2(y+5)+2y=40 2y+10+2y=40 4y+10=40 4y=30 4y=7.5 x=7.5+5 x=12.5 AREA: 12.5 x 7.5 = 93.75 YARDS

A rectangle has 4 sides. Let the width of the rectangle be y. As the length of the rectangle is twice its width, it is 2y. The sum of the 2 sides that are the width: 2 * y = 2y The sum of the 2 sides that are the length: 2y * 2 = 4y The perimeter equals the 2 widths and the 2 breadths: 2y + 4y = 6y The perimeter: 6y = 60 cm So: y = 10 cm The length is 2y = 2 * 10 cm = 20 cm Answer: 20 cm

L = 3x + 2y

Add together the lengths of each of its sides.

Look at it this way, suppose x is one side of the rectangle and y is the other. Then the area of the rectangle would be xy. Now if you double each side of the originial rectangle you would have each side as 2x and 2y. So the area of the new rectangle would be 2x*2y or 4xy. As you can see the new area is 4 times larger than the original.

To find the perimeter of a polygon, just add the length of all the sides. In this case, the four sides of the rectangle.

x y y y y y Perimeter of each rectangle = 2x + 2y = 30 which can be reduced: x + y = 15 Thus the perimeter of square = 2x + 10y Since it is a square: x = 5y Replacing values in equation: 2(5y) + 2y = 30 Solving for y: 10y + 2y = 30 : 12y = 30 : y = 2.5 Which means x = 12.5 Area of square = (12.5)2 = 156.25 cm2 Checking that numbers fit original: 2(12.5) + 2(2.5) = 25 + 5 = 30

X+y^2+2y=-1

X^2y

Perimeter is the sum of all of the sides, so perimeter can be written as P=2x + 2y First you need to plug in the values you know 360 = 2(84) + 2y Multiply 360=168 + 2y Subtract 192=2y and divide y=96 feet so the length is 96 feet
