Best Answer

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

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

Another Answer:The length of the rectangle is 29 cm because 2*(29+23) = 104 cm which is the perimeter

2 * 12 + 2 * 2.5 = 29

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

The perimeter is 11 + 5 + 13 = 29 inches.

Perimeter = (1 + 29 + 1 + 29) = 60 ft Area = (1 x 29) = 29 square feet

Anything more than 21. (29 + 21 + 29 + 21) = 100

2 * 12 + 2 * 2.5 = 29

Area = length x width, so length = area/width = 116/4 = 29 yds

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

It is: 45*29 = 1305 square cm
