The perimeter of a rectangle can be calculated by adding up the lengths of all its sides. In this case, the rectangle is 7 inches by 8 inches, so its perimeter would be 2(7) + 2(8) = 14 + 16 = 30 inches.

The apostrophe in 7' means 7 inches. This means that there would be two 7 inch sides to the rectangle and two 8 inch sides. Perimeter = 7+7+8+8= 30 inches.

If a rectangle is 40 inches. the rectangle is 12 inches long then: 2 * 12 + 2 * width = 40 2 * width = 40 - 2*12 = 40 - 24 = 16 width = 16 / 2 = 8 So the width of the rectangle is 8.
Let the width of the rectangle be represented by "w" inches. Since the length is twice the width, it can be expressed as "2w" inches. The formula for the perimeter of a rectangle is P = 2(l + w), where P is the perimeter, l is the length, and w is the width. Substituting the given values into the formula, we get 48 = 2(2w + w). Simplifying, we find that 48 = 6w. Solving for w, we find that the width of the rectangle is 8 inches, and the length is 16 inches.
Perimeter = 12 + 12 + 8 + 8 = 40.
