No triangle exists that minimizes that condition. However, the infinum of the perimeters of all such triangles = twice the distance from (a,b) to the line y = x. That's just an application of the triangle inequality after picking the first two points (one is on the line, the other is (a,b)) of any triangle.
The perimeter of an equilateral triangle exceeds the perimeter of a square by 1989cm. The length of each side of the triangle exceeds the length of each side of the square by d cm. The square has perimter greater than 0. How many positive integers are not possible values for d? t for side of...
A pentagon is formed by placing an isosceles triangle on a rectange. If the pentagon has fixed perimeter P, find the lengths of the sides of the pentagon that maximize the area of the pentagon. Check number 4 for a picture and answers...
so where do i start for this problem? the length l of a rectangle is decreasing at the rate of 2 cm/sec while the width w is increasing at the rate of 2 cm/sec. when l=12cm and w= 5cm, find the rates of change of area, perimeter, and the lengths of the diagonals of the rectangle.
One side of a rectangle is three times the other. If the perimeter increases by 2%, what is the percentage increase in area? I've started with these few...
To granddad Really sorry if i am getting back to you on this. For the first question perimeter of square , the data was the following: Upper bound perimeter=27.26cm Lower bound perimeter=27.22cm Give the perimeter of the square to an appropriate degree of accuracy As you said The true value of the perimeter lies between 27.22 cm and 27.26 cm.
