18 feet
Do-it-in-your-head method: Length + width equals half the perimeter, ie 106; 106 - 8 = 98; half of 98 is 49 which is the width, making the length 57.
All 4 sides of a square have equal length. If the perimeter is 28 ft, then the length of each side is 7 ft. In any rectangle, the area is (length) times (width). In the square, (length) times (width) is the same as (side squared). 72 = 49 square feet.
For a square, the area is the length of a side squared and the perimeter is 4 times the length. If the area is 49, then the length of a side is 7. The perimeter is then 4 times 7, or 28.
I think this means we have a shape with a perimeter 39cm and we are asked what is the smallest area. It is a rectangle of length 19.5cm and width zero. Or perhaps it should read area 49 cm squared., what is the smallest periimeter. A circle with 49=pi x r2. Then perimeter=pi x 2r
L + W = P/2 = 49 so Length must be greater than 35 cm

28 meters It would be a square because A = L x W so 49 = 7 x W and the width is 7. Its perimeter is 4*7 = 28 meters.
For a square, the area is the length of a side squared and the perimeter is 4 times the length. If the area is 49, then the length of a side is 7. The perimeter is then 4 times 7, or 28.

Area = 49 cm2 => length of side = 7 cmThen perimeter = 4*7 = 28 cm.Area = 49 cm2 => length of side = 7 cmThen perimeter = 4*7 = 28 cm.Area = 49 cm2 => length of side = 7 cmThen perimeter = 4*7 = 28 cm.Area = 49 cm2 => length of side = 7 cmThen perimeter = 4*7 = 28 cm.
The perimeter actually doesn't tell you anything about the breakdown betweenthe length and width. All we can tell about this one is that the sum of (length+width)has to be 98 inches. That still leaves an infinite number of possible rectangles.If the perimeter is 196 inches and the length has to be the longer dimension, thenit can be anything more than 49 inches, with no upper limit.For example:Width = 1 millionth of an inchLength = 1 millionth of an inch less than 98 inchesPerimeter = 196 inches.
49 inches life sized
L + W = P/2 = 49 so Length must be greater than 35 cm
Since the area is given as 49, it means the room is in the shape of a square. Since all sides of a square are equal, the width of the room would also be 7.
Area of a square can be calculated using the formula A = a^2, where "a" is the length of a side of the square. Its perimeter is P = 4*a. 49 = a^2 => a = 7cm P = 4*7 = 28cm The perimeter of the square is 28cm.
