The length of the rectangle is x cm and the width is 2 cm. Write down the perimeter of this rectangle

The length of the rectangle is x cm and the width is 2 cm. Write down the perimeter of this rectangle as different expressions. Write down its semiperimeter as an expression.

The perimeter of a rectangle is the sum of the lengths of all its sides.
a = x cm – the length of the rectangle;
b = 2 cm – the width of the rectangle.
Expressions for finding the perimeter:
P = x + x + 2 + 2.
P = 2 * x + 2 * 2.
P = 2 * (x + 2).
The sum of the length and width of a rectangle is called a semi-perimeter.
p = P / 2.
p = (x + 2).
