Question

13. The width of a rectangle is (x + 2)/5 cm. The rectangle’s length is (x2 + 3x + 2)/(x + 3) cm. What expression represents the perimeter of this rectangle?

Answer 1

P = 2(x + 2)/5 + 2 (x^2 + 3x + 2/(x + 3).

Explanation:

The perimeter P = 2 * width + 2 * length.

Here P = 2(x + 2)/5 + 2 (x^2 + 3x + 2/(x + 3)
