Sometimes perimeter and area questions can be combined with other sections of the course such as managing money. In this case you will also have to work out a cost. A garden is in the shape of a ...
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.
Use the figure to find the approximate perimeter of RSTU. A) 72.5 in. B) 73.6 in. C) 72.0 in. D) 73.0 in. E) 71.8 in. B you have to find the length of the sides first ...
