How do you draw a rectangle with an area of 7 with a perimeter of 29?

The rectangle is 14 units x 0.5 units:
Let a and b be the dimensions of the rectangle
Perimeter = 2a + 2b = 29
2a + 2b = 29
=> a + b = 14.5
=> b = 14.5 - a
Area = a * b = 7
=> a * (14.5 - a) = 7
=> 14.5a - a2 = 7
=> a2 - 14.5a + 7 = 0
Solving the quadratic equation gives a=14 or a=0.5

What if the width of a rectangle is 23 centimeters. If the perimeter of the rectangle is 104 centimeters what is the length?
Another Answer:The length of the rectangle is 29 cm because 2*(29+23) = 104 cm which is the perimeter
What is the perimeter of a rectangle if the length is 12 yards and the width is 2 and a half?
2 * 12 + 2 * 2.5 = 29
What are the dimensions of a rectangle that has a perimeter of 29 cm and an area of 50.3125 square cm?
Let the dimensions be x and y:- If: 2x+2y = 29 then y =14.5-x If: xy = 50.3125 then x(14.5-x) = 50.3125 Expanding brackets and transposing terms: 14.5x -x^2 -50.3125 = 0 Using the quadratic equation formula: x = 8.75 or x = 5.75 Therefore dimensions of the rectangle are: length = 8.75 cm and width = 5.75 cm Check: 2(8.75+5.75) = 29 cm Check: 8.75*5.75 = 50.3125 square cm

If the perimeter of the rectangle is 60m find its area?
You can't tell the area from the perimeter. There are an infinite number of rectangles that all have the same perimeter but different areas. Here are a few that all have perimeter of 60 m: 1 x 29 . . . . . area = 29 2 x 28 . . . . . 56 3 x 27 . . . . . 81 4 x 26 . . . . 104 5 x 25 . . . . 125 6 x 24 . . . . 144 7 x 23 . . . . 161 8 x 22 . . . . 176 9 x 21 . . . . 189 10 x 20 . . . 200 12 x 18 . . . 216 14 x 16 . . . 224 15 x 15 . . . 225 0.1 x 29.5 . . area = 2.95
