Zahra cuts out a rectangle that has a perimeter of 22 inches and a length of 9 inches. She cuts out another rectangle that is the same length and twice as wide.
What is the perimeter of the new rectangle?
inch(es)
The rectangle has a length of 9 inches, so the width of the second rectangle is twice the length, which is 9*2 = <<9*2=18>>18 inches.
The perimeter of the new rectangle is given by 2 times the sum of the length and the width, which is 2*(9+18) = 2*27 = <<2*(9+18)=54>>54 inches. Answer: \boxed{54}.
To find the perimeter of a rectangle, you add up the lengths of all its sides.
Given that the length of the first rectangle is 9 inches, we can determine the width of the first rectangle by using the formula for the perimeter of a rectangle:
P = 2(l + w)
Substituting in the values we know:
22 = 2(9 + w)
Dividing both sides by 2:
11 = 9 + w
Subtracting 9 from both sides:
2 = w
So the width of the first rectangle is 2 inches.
For the second rectangle, we know that it has the same length as the first rectangle (9 inches) and twice the width.
Therefore, the width of the second rectangle is 2 * 2 = 4 inches.
To find the perimeter of the new rectangle, we can use the same formula:
P = 2(l + w)
Plugging in the values:
P = 2(9 + 4)
P = 2(13)
P = 26
So the perimeter of the new rectangle is 26 inches.
To find the perimeter of a rectangle, you need to add up the lengths of all four sides.
Given that Zahra cuts out a rectangle with a length of 9 inches, we can calculate the width of the rectangle using the information that it is twice as wide as the original rectangle. Therefore, the width of the new rectangle would be 2 times 9 inches, which is 18 inches.
To find the perimeter of the new rectangle, add up the lengths of all four sides:
Perimeter = 2 * (length + width)
Perimeter = 2 * (9 inches + 18 inches)
Perimeter = 2 * 27 inches
Perimeter = 54 inches
Therefore, the perimeter of the new rectangle is 54 inches.
