A rectangle has a length of 6 meters and a perimeter of 20 meters. What is the width of the rectangle?
A. 4 meters
B. 7 meters
C. 14 meters
D. 52 meters
C ?
No.
i think this is great
To find the width of the rectangle, we need to subtract twice the length from the perimeter.
Step 1:
The formula for the perimeter of a rectangle is P = 2L + 2W, where P is the perimeter, L is the length, and W is the width.
Step 2:
Given that the length of the rectangle is 6 meters and the perimeter is 20 meters, we can substitute these values into the formula:
20 = 2(6) + 2W
Step 3:
Simplifying the equation:
20 = 12 + 2W
Step 4:
Subtracting 12 from both sides of the equation:
8 = 2W
Step 5:
Dividing both sides of the equation by 2:
W = 4
Based on the calculations, the width of the rectangle is 4 meters, so the correct answer is A. 4 meters.
To find the width of the rectangle, we can use the equation for the perimeter of a rectangle which is:
Perimeter = 2 * (Length + Width)
Given that the length is 6 meters and the perimeter is 20 meters, we can substitute these values into the equation and solve for the width:
20 = 2 * (6 + Width)
Divide both sides of the equation by 2:
10 = 6 + Width
Subtract 6 from both sides of the equation:
10 - 6 = Width
Width = 4
Therefore, the width of the rectangle is 4 meters. So, the correct answer is A.
