The length of the rectangle is 24 cm. This is 4 times its width. Find the perimeter and area of this rectangle.

Let’s find the width of the rectangle:
24: 4 = 6 cm;
A rectangle is a shape whose opposite sides are equal. The perimeter is the sum of the lengths of all sides. Since the opposite sides are equal, then P = 2a + 2b.
P = 2 * 24 + 2 * 6 = 48 + 12 = 60 cm;
To find the area of a rectangle, you need to multiply the length by the width.
S = a * b, S = 24 * 6 = 144 cm ^ 2.
Answer: P = 60 cm, S = 144cm ^ 2.
