Answer:
P: 26cm, A:36cm
Step-by-step explanation:
Remember, the perimeter of a rectangle is all of the sides added up. We already know the width is 4cm and the length is 9cm, and since the opposite sides are the same (the lenghts are the same size, the width are always the same size), we know that we have 2 4cm sides and 2 9cm sides.
Add: 4 + 4 + 9 + 9 and that is your perimeter.
The area is the length and width multiplied together:
Multiply: 9 x 4 and that is your area.
