The side length of the top of square table is x. The expression for perimeter is:
(a) 4 + x
(b) 2x
(c) 4x
(d) 8x

Solution:

Given, the side length of the top of the square table is x.

We have to find the expression for perimeter.

Perimeter is the total length of the boundary of any closed shape.

Perimeter = sum of all sides

Perimeter of square = 4(side)

= 4x

Therefore, the perimeter is 4x.

✦ Try This: The side length of the top of square table is 5x. The expression for perimeter is:

Given, the side length of the top of the square table is 5x.

We have to find the expression for perimeter.

Perimeter is the total length of the boundary of any closed shape.

Perimeter = sum of all sides

Perimeter of square = 4(side)

= 4(5x)

= 20x

Therefore, the perimeter is 20x.
