22. The length of a rectangle is two times its breadth. Its perimeter is 60 cm.
(a) If the breadth of rectangle is x cm, the length of the rectangle is ________.
(b) Perimeter in terms of x is ________.
(c) The equation formed is ________.
(d) The solution of the equation is ________.
(a) 2x
(b) 6x or 2(2x + x)
(c) 6x = 60
(d) 10
Breadth = x, Length = 2x. Perimeter = 2(L + B) = 6x. 6x = 60 ⇒ x = 10.
