The side of the rectangle is 4 cm and the length is 5 cm less. Find the perimeter and area of this rectangle?

1. Find the length of the rectangle if it is known that it is 5 mm less than the adjacent side:
4 cm – 5mm = 4 cm – 0.5 cm = 3.5 cm.
2. Find the perimeter of the rectangle by multiplying the sum of its adjacent sides by 2:
Perimeter = (3.5 + 4) * 2 = 7.5 * 2 = 15 cm.
3. Find the area of the rectangle, which is equal to the product of its adjacent sides:
Area = 4 * 3.5 = 14 cm2.
Answer: the area of the rectangle is 14 cm2, and its perimeter is 15 cm.
