the perimeter of a rectangular painting is 344 cm if the length of painting is 91 cm what is its width?

2(w+91) = 344

To find the width of the rectangular painting, we can use the formula for the perimeter of a rectangle, which is given by:

Perimeter = 2(Length + Width)

In this case, the perimeter is given as 344 cm, and the length is 91 cm. We need to solve for the width.

Let's substitute the given values into the formula:

344 = 2(91 + Width)

To solve for the width, we can start by simplifying the equation:

344 = 2(91 + Width)
Divide both sides by 2:

172 = 91 + Width
Next, subtract 91 from both sides:

172 - 91 = Width
81 = Width

Therefore, the width of the rectangular painting is 81 cm.

To find the width of the rectangular painting, we can use the formula for the perimeter of a rectangle:

Perimeter = 2(length + width)

Given that the perimeter is 344 cm and the length is 91 cm, we can substitute these values into the formula and solve for the width:

344 = 2(91 + width)

To solve for the width, let's isolate it:

344 = 182 + 2width

Subtract 182 from both sides:

162 = 2width

Divide both sides by 2:

81 = width

Therefore, the width of the rectangular painting is 81 cm.
