The area of a rectangle is given by rectangle Area $=$ rectangleLength $**$ rectangleWidth. Read double variables rectangleLength and rectangleWidth from input, respectively. Then, compute rectangleArea using the formula. Finally, output "Rectangle area is $"$ followed by the value of rectangleArea to three digits after the decimal point. End with a newline. Ex: If the input is $10\mathrm{.}09\mathrm{.}0,$ then the output is:

Rectangle area is $90\mathrm{.}000$
