11. The length of a rectangular verandah is 3 m
more than its breadth. The numerical value of
its area is equal to the numerical value of its
perimeter
(i) Taking x as the breadth of the verandah,
write an equation in x that represents the
above statement.
..
(ii) Solve the equation obtained in (i) above
and hence find the dimensions of the

Answer:
m. Perimeter = 2(x + x + 3) = (4x + 6)m. ∴ x = 3 and x = - 2 (inadmissiable). Hence breadth = 3m, length = 6m
