In order to find the area and perimeter, we first need to find the length, for this we add 5 cm to the width:

4 + 5 = 9 (cm).

We calculate the perimeter by the formula:

P = 2 * (a + b), where a – width, b – length.

P = 2 * (4 + 9) = 2 * 13 = 26 (cm).

We find the area by the formula:

S = a * b

S = 4 * 9 = 36 (cm2).
