What is the perimeter of a rectangle 7' by 8'?
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.
What is the perimeter of a rectangle 48 inches and 8 inches in length?
112 inches
The perimeter of a a rectangle is 40 inches. the rectangle is 12 inches long. How wide is the rectangle?
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.
The length of a rectangle is twice the width width the perimeter is 48 in find the dimensions of the rectangle?
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.
How do you find the perimeter of a rectangle 12x8?
Perimeter = 12 + 12 + 8 + 8 = 40.
