the perimeter of a rectangle is 200cm. If the length:breadth = 3:2 find the area of the rectangle.
----
3:2 is the same as 3x:2x where length = 3x and breadth = 2x.
-----
Equation:
Perimeter = 2(length + breath)
200 = 2(3x + 2x)
100 = 5x
x = 20
----
length = 3x = 3*20 = 60
breath = 2x = 2*20 = 40
---------
Cheers,
