Calculate :
length of a rectangle having area `10.25 cm^(2)` and breadth 2.5 cm

Length of rectangle 15 cm has its area 150" cm"^2 . Find its breadth.

The length of a rectangle is increasing at the rate of 3.5 cm/sec and its breadth is decreasing at the rate of 3cm/sec. Find the rate of change of the area of the rectangle when length is 12 cm and breadth is 8 cm.

The length of a rectangle is 7.1 cm and its breadth is 2.5 cm. What is the area of the rectangle?
