The circumference is the perimeter of a circle. It is a length and so is measured in (mm), (cm), (m) or (km). An area is measured in square units: (mm^{2 ...
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...
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...

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.
