Question

Help me find the perimeter of this square. if you can do it step by step please!

Answer 1

The perimeter of the square is 113.4 meters.

Step-by-step explanation:

To find the perimeter of a square, you need to add up the lengths of all four sides. In this case, the square has a length of 39.2 meters and a width of 17.5 meters. Since all sides of a square are equal, the perimeter can be calculated by adding up all four sides: P = 39.2 + 17.5 + 39.2 + 17.5 = 113.4 meters.

Answer 2

396

Step-by-step explanation:

It's a square.

That means that all four sides are equal.

So the two expressions you have been given are equal.

2.5x + 76.5 = 12x - 9 Subtract 2.5x from both sides.

-2.5x -2.5x

76.5 = 9.5x - 9 Add 9 to both sides

9 9

85.5 = 9.5x Divide by 9.5

85.5/9.5 = x

x = 9

That is just the value for x. It is not the answer

Side = 12x - 9

Side = 12*9 - 9

Side = 108 - 9

Side = 99

The perimeter = 4 * Side

The perimeter = 4 * 99

Perimeter = 396
