The rectangle is 9 inches wide X 27 inches long. Clue: width is X; length is 3 times width (3X). Perimeter is width plus length times two (X + 3X times 2 = 8X). 8X = 72; X = 9. 3X = 27. Proof: 9 + 9 (2sides) +27 + 27 (2 lengths) = 72.
A rectangle has two dimensions, length and width. You haven't said what the width is. The perimeter is the distance around the rectangle. Imagine going round it. You would go 42 inches, then a width, then another 42 inches, then another width. In general, the perimeter of a rectangle is twice its length plus twice its width.
Its dimensions are 6 inches by 7 inches because 2(6+7)=26 inches and 6*7=42 square inches
The perimeter would be 36 inches.
Length of rectangle is 5 inches and its width is 4 inches Check: 2*(5+4) = 18 inches which is its perimeter
4
The dimensions of the rectangle are 3 inches by 14 inches
The length of a rectangle is 8 inches. The width of the rectangle is 4 inches. What is the perimeter of the rectangle in inches?

Its dimensions are 6 inches by 7 inches because 2(6+7)=26 inches and 6*7=42 square inches
That would be 3 x 9 inches.
If you mean a 3 inches by 4 inches rectangle then its perimeter is 14 inches
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 area of a rectangleis 100 square inches. The perimeter of the rectangle is 40 inches. A second rectangle has the same area but a different perimeter. Is the secind rectangle a square? Explain why or why not.
You must first calculate the width, using the formula for the area of a rectangle (plug in the numbers you know into the formula, and solve for width). Once you know this, you can plug in the numbers in the formula for a rectangle's perimeter.
The perimeter would be 36 inches.
yes
The perimeter is 60 inches
