The area of a rectangle is 45 square inches. One dimension is 5 inches. What is the perimeter?

45 / 5 = 9

P = (2 * 5) + (2 * 9)

P = ?

To find the perimeter of a rectangle, we need to know the length and width of the rectangle. From the given information, we know that one dimension is 5 inches. Let's assume that the other dimension is represented by the variable "x".

We know that the area of a rectangle is given by the formula: Area = length * width

In this case, the area is given as 45 square inches and one dimension is 5 inches. Substituting these values into the formula, we get:

45 = 5 * x

To solve for x, divide both sides of the equation by 5:

45/5 = x

9 = x

So, the other dimension of the rectangle is 9 inches.

To find the perimeter of a rectangle, we use the formula: Perimeter = 2 * (length + width)

Plugging in the values, we have:

Perimeter = 2 * (5 + 9)
Perimeter = 2 * 14
Perimeter = 28 inches

Therefore, the perimeter of the rectangle is 28 inches.

To find the perimeter of a rectangle, you need to know the lengths of its sides. In this case, you are given the area and one dimension.

Let's denote the length of the rectangle as "l" and the width as "w." Given that the area of the rectangle is 45 square inches and one dimension is 5 inches, we can set up the equation lw = 45.

Since we know that one dimension is 5 inches, we can substitute that into the equation: 5w = 45.

To find the width, divide both sides of the equation by 5: w = 9.

Now that we have both dimensions, we can calculate the perimeter of the rectangle. The formula for the perimeter of a rectangle is P = 2(l + w).

Substituting the known values, we have P = 2(5 + 9).

Evaluating the equation, we find that P = 2(14) = 28.

Therefore, the perimeter of the rectangle is 28 inches.
