Final answer:
The perimeter of the rectangle is 26 cm and the area is 40 cm².
Step-by-step explanation:
To find the perimeter of a rectangle, you add up the lengths of all four sides. In this case, the dimensions of the rectangle are 8 cm and 5 cm. So, the perimeter is 2(8 cm) + 2(5 cm) = 16 cm + 10 cm = 26 cm.
To find the area of a rectangle, you multiply its length by its width. In this case, the length is 8 cm and the width is 5 cm. So, the area is 8 cm × 5 cm = 40 cm².
