1The continuous line forming the boundary of a closed geometrical figure.
‘the perimeter of a rectangle’
‘He compares the areas of figures with equal perimeters and volumes of solids with equal surface areas, proving a result due to Zenodorus that the sphere has greater volume than any regular solid with equal surface area.’
‘The number four, for example, would be the ratio of the perimeter of a square to one of its sides and also the ratio of the area of a square to the area of a square whose side is half the original.’
‘Then these rings also have the additional property that both the inner perimeters are equal and the outer perimeters are equal.’
‘Zenodorus studied the area of a figure with a fixed perimeter and the volume of a solid figure with fixed surface.’
‘Answer: the arc lengths and, therefore, the perimeters are equal.’
‘The perimeter of the inner polygon is shorter than the circumference of the circle, while that of the outer polygon is longer.’
‘Finally, if the rope is short enough (less than half the perimeter of the barn), the problem simplifies immensely.’
‘The most interesting results show, with a very ingenious proof, that an equilateral triangle has a greater area than any isosceles or scalene triangle with the same perimeter.’
‘You calculate the perimeter by multiplying the diameter by pi.’
‘It is easier to find a pentagon that circumscribes the same circle as the given square and has the same perimeter.’
‘The square and the cube are abstract, they're mathematical forms, measurements, perimeters, boundaries, mental constructs, and as such, are emotionally unknowable.’
‘We found that the area, perimeter, length, and width of the lamina were highly correlated, suggesting the existence of a common genetic control.’
