To find the width of a rectangle, we can use the formula for the perimeter:
Perimeter = 2(length + width)
Given that the length is 15 and the perimeter is 90, we can substitute these values into the formula:
90 = 2(15 + width)
Dividing both sides by 2:
45 = 15 + width
Subtracting 15 from both sides:
30 = width
Therefore, the width of the rectangle is 30.
To find the width of a rectangle with a perimeter of 90 and a length of 15, we can use the formula for the perimeter of a rectangle, which is given by:
Perimeter = 2(length + width)
Given that the length is 15, we can substitute this value into the formula:
90 = 2(15 + width)
Now we can solve for the width:
90 = 30 + 2*width
Subtracting 30 from both sides, we get:
60 = 2*width
Dividing both sides by 2, we have:
30 = width
So, the width of the rectangle is 30.
To find the width of a rectangle with a given perimeter and length, you need to use the formula for the perimeter of a rectangle, which is P = 2(L + W), where P is the perimeter, L is the length, and W is the width.
In this case, the perimeter is given as 90 and the length is given as 15.
Plugging in the values into the formula, we get:
90 = 2(15 + W)
Now, to solve for W, we can start by simplifying the equation:
90 = 30 + 2W
Subtracting 30 from both sides of the equation:
90 - 30 = 2W
60 = 2W
Dividing both sides of the equation by 2:
60/2 = W
W = 30
Therefore, the width of the rectangle is 30 units.
