The width of the rectangle is 60 cm, which is 4/5 of its length. Calculate the perimeter and area of the rectangle.

Let’s calculate the length of the rectangle:

60: 4/5 = 60 * 5/4 = 75 cm.

Let’s calculate the perimeter of the rectangle:

P = (a + b) * 2 = (60 + 75) * 2 = 135 * 2 = 270 cm.

270 cm = 2 m 70 cm.

Let’s calculate the area of the rectangle:

S = a * b = 75 * 60 = 4500 cm²

Answer: the perimeter of the rectangle is 270 cm, and its area is 4500 cm²
