The length of a triangle can't be expressed in square units and only its area is expressed in square units
The length of a string is typically measured in centimeters or millimeters, so it can be measured to the nearest centimeter by rounding the measurement to the closest whole number.
There is no line specified. The ideal line, in geometry, is of infinite length.
We can use either meter or centimeter to measure a rectangle. For a large area of rectangle we can also use "feet" or " yards". Using "meter" is a convenient form to measure the length of the rectangle.
5 cm
The perimeter of a rectangle is equal to twice the length plus twice the width, so P = 2l + 2w P = (2x25) + (2x13) P = 50 + 26 P = 76 centimeters
42 cm
Perimeter of a rectangle is 2(l+b).Area of rectangle is 216 centimeter square.
A golden rectangle is a rectangle where the ratio of the length of the short side to the length of the long side is proportional to the ratio of the length of the long side to the length of the short side plus the length of the long side. It is said to have the "most pleasing" shape or proportion of any rectangle. The math is like this, with the short side = s and the long side = l : s/l = l/s+l Links can be found below to check facts and learn more. In ratio terms, the Golden Rectangle has a width/height ratio of 1.618/1.
