What is the perimeter of a rectangle that is 18 inches wide and 23 inches long?
P = 2(l+w)
l = 23, w = 18
P = 2(23 + 18)
P = 2(41)
P = 82
So the perimeter of the rectangle is 82 inches.

Answer:
His age is 7 years.
Step-by-step explanation:
Let Rehman's present age be x years.
1 / (x - 3) + 1 /(x + 5) = 1/3
Multiply through by the LCD 3(x - 3)(x + 5):
3(x + 5) + 3(x - 3) = (x + 5)(x - 3)
3x + 15 + 3x - 9 = x^2 + 2x - 15
x^2 + 2x - 6x - 30 + 9 = 0
x^2 - 4x - 21 = 0
(x - 7)(x + 3) = 0
x = 7 (answer).
