| First, we determine the length of this rectangle.
To do this, divide the known width by 60%.
We get:
36/60% = 36 / 0.6 = 60 cm.
We find the perimeter.
To do this, multiply the sum of the length and width of the rectangle by 2, or sum the lengths of all sides.
We get:
2 * (60 + 36) = 2 * 96 = 192 cm.
Or:
60 + 36 + 60 + 39 = 120 + 72 = 192 cm.
Determine the area.
We multiply the length by the width.
60 * 36 = 2160 cm2
Answer: Perimeter 192 cm, area 2160 cm2 (square centimeter).
