The length of the ABCD rectangle is a cm, and the width is 3 times less than the length. Find the pyrimeter of the rectangle with a = 18.
To find the perimeter of a rectangle, fold the 4 sides of the rectangle.
P = a + b + a + b.
a = 18 cm.
b = 18/3 cm. = 6 cm.
Now let’s calculate the perimeter of the rectangle:
P = 18 cm + 18 cm + 6 cm + 6 cm = 48 cm.
Answer: The perimeter of the rectangle is 48 centimeters.
