If the perimeter and diagonal of a rectangle are 14 and 5 cms respectively, find its area.

The length of a rectangle is decreasing at the rate of 5 cm/minute and the width is increasing at the rate of 4cm/minute. When lenght is 3 cm and width is 2 cm , find the rates of change of the perimeter and the area of the rectangle.

Area and perimeter of a rectangle

The length of a rectangle is decreasing at the rate of 2 cm/sec and the width is increasing at the rate of 2 cm/sec. When x=10 cm and y=6 cm , find the rate of change of (i) the perimeter (ii) the area of the rectangle.

The length x of a rectangle is decreasing at the rate of 5cm/minute and the width y is increasing at the rate of 4cm/minute.~ Whenx=8cm and y=6, find the rates of change of (i) the perimeter (ii) the area of the rectangle.

A rectangle and a square are of equal area.If the length and the perimeter of a rectangle are 25cm and 58cm respectively,then find the perimeter and area of the square?

The perimeter of a square = 4s Area of a square = s xx s Perimeter of a rectangle = 2 (l + b) Area of a rectangle = l xx b If length is thrice of the breadth of a rectangular hall. Find the perimeter of the rectangle.
