It could be: 4n = 20 and so n = 5 feet
You need to write two equations with two variables each, for the two facts. Remembering that the perimeter is the sum of the lengths of all the sides:Write an equation for the perimeter of the original rectangle:perimeter = 2(length + width)26 = 2(l+w) (equation 1)Write an equation for the area of the increased rectangle:A = length x widthA = (l+4)(w+3) (equation 2)Solve the two equations simultaneously; and you'll get the width and length of the original rectangle.
Write an algorithm to find the root of quadratic equation
This question has no unique answer. A (3 x 2) rectangle has a perimeter = 10, its area = 6 A (4 x 1) rectangle also has a perimeter = 10, but its area = 4 A (4.5 x 0.5) rectangle also has a perimeter = 10, but its area = 2.25. The greatest possible area for a rectangle with perimeter=10 occurs if the rectangle is a square, with all sides = 2.5. Then the area = 6.25. You can keep the same perimeter = 10 and make the area anything you want between zero and 6.25, by picking different lengths and widths, just as long as (length+width)=5.
if a line has a slope of -2 and a point on the line has coordinates of (3, -5) write an equation for the line in point slope form
A regular hexagon is a shape that has 6 equal sides. x = length of a side 6x = perimeter of hexagon pond
The perimeter of a square is 400 meters. write an equation for the perimeter and solve for the length of one side
4x12
Here is what you are supposed to do: * Convert to consistent units. For example, convert the cm to mm. * Write an equation for the diagonal (in terms of length and width). Replace the known diagonal. * Write an equation for the area, in terms of length and width. * Solve the two equations simultaneously. * Calculate the perimeter.
Write an equation for the perimeter, and solve it. Remember that the perimeter is the sum of all four sides.
Sure, honey. First, let's keep it simple. To calculate the perimeter of a square, you just need to multiply the length of one side by 4. So, if the side length is "s", the formula is 4s. As for the flowchart, draw a square with "s" labeled on one side, then an arrow pointing to a box that says "Perimeter = 4s". Done and done, darling.
s=side length P=perimeter P=4s

Perimeter covers the boundary line of any plane figure.
The area of rectangle is : 13832.797999999999
Write two simultaneous equations and solve them. One for the perimeter, one for the area.
Here are the key aspects of work; I'll leave the details of the calculation to you. 1) Write an equation for the area, in terms of variables "w" and "h" (for width and height). 2) Write an equation for the length of the diagonal, in terms of "w" and "h". (Hint: Use the Pythagorean Theorem.) 3) Solve the two equations. 4) Calculate the perimeter, based on length and width.
I suggest that you do the following:* Convert the meters to centimeters, to have compatible units.* Write the equation for the area of the rectangle. Replace the variable "a" (area) with the known area.* Write the equation for the perimeter of a rectangle. Replace the variable for the perimeter with the known perimeter (in cm).* Use any method to solve the simultaneous equations.Another Answer:-Let the dimensions be x and yIf: 2x+2y = 100 then x+y = 50 and x = 50-yIf: xy = 600 then (50-y)y = 600 and so 50y-y2-600 = 0Solving the quadratic equation: y = 20 or y = 30Therefore by substitution the dimensions are: when y = 20 cm then x = 30 cm
