Condition: the width of the rectangle is 1dm 2cm and it is 8cm less than the length. Calculate the perimeter and area of the rectangle.
Decision.
Width is 1dm 2cm = 12cm. The length is 8 cm longer, which means it is 20 cm.
The perimeter is the sum of all sides of the rectangle, that is, P = 2 (12 + 20) = 64 cm.
The area is the product of its two sides, that is, S = 12 * 20 = 240 (cm²)
