find the width of a rectangle with a perimeter of 90 and a length of 15
To find the width of a rectangle, we can use the formula for the perimeter of a rectangle:
Perimeter = 2 * (Length + Width).
In this case, we know the perimeter is 90 and the length is 15.
So, we can substitute these values into the formula and solve for the width:
90 = 2 * (15 + Width).
Dividing both sides of the equation by 2:
45 = 15 + Width.
Subtracting 15 from both sides of the equation:
45 - 15 = Width.
30 = Width.
Therefore, the width of the rectangle is 30.
To find the width of a rectangle with a given perimeter and length, we can use the formula for the perimeter of a rectangle:
Perimeter = 2(length + width)
In this case, the perimeter is 90 and the length is 15. We can substitute these values into the formula and solve for the width:
90 = 2(15 + width)
Let's simplify the equation:
90 = 30 + 2*width
Subtract 30 from both sides:
90 - 30 = 30 + 2*width - 30
60 = 2*width
Divide both sides by 2:
60/2 = 2*width/2
30 = width
Therefore, the width of the rectangle is 30.
So, the width of the rectangle is 30 units.
To find the width of a rectangle, we can use the formula for the perimeter of a rectangle, which is given by the equation:
Perimeter = 2 * (Length + Width)
In this case, we are given the perimeter as 90 and the length as 15. Plugging these values into the formula, we get:
90 = 2 * (15 + Width)
To find the width, we first need to isolate the variable.
Dividing both sides of the equation by 2 gives us:
45 = 15 + Width
Next, we can subtract 15 from both sides of the equation:
45 - 15 = Width
30 = Width
Therefore, the width of the rectangle is 30 units.
