Answer 3

Perimeter of the Rectangle:

The perimeter of a rectangle can be calculated using the formula: P = 2 * (length + width).

Given: Length (a) = 9 cm Width (b) = 5 cm

Using the formula, the perimeter (P) can be calculated as: P = 2 * (a + b) P = 2 * (9 + 5) P = 2 * 14 P = 28 cm.

Area of the Rectangle:

The area of a rectangle can be calculated using the formula: A = length * width.

Given: Length (a) = 9 cm Width (b) = 5 cm

Using the formula, the area (A) can be calculated as: A = a * b A = 9 * 5 A = 45 cm^2
