Rectangle area = (rectangle width) x (rectangle height)
A = lw Area of a rectangle = length times width
The area of rectangle is : 45.0
The area of rectangle is : 72.0
Well its lw=a so quadrupling it would make it (L4)W=A or lw4
Suppose a rectangle has a base x and a side y. The equation for the area A of a rectangle is A=x*y. Quadrupling both side and base means both are now 4x and 4y. Now, the new area, which I shall call A' will be described by the formula A'=4x*4y, which turns into A'=16xy. In the end, the new area is equal to sixteen times the original area. Try it with any possible combination of numbers, should always give sixteen times the original area, as long as you are only quadrupling the original lengths.
quadruples it

Quadrupling the base radius will do that.
Rectangle area = (rectangle width) x (rectangle height)
A = lw Area of a rectangle = length times width
The area of rectangle is : 35.0
It's half the area of a rectangle
The area of rectangle is : 168.0
The area of rectangle is : 30.0
The area of rectangle is : 48.0
