Find the width of a rectangle with a perimeter of 90 and a length of 15. (1 point) Responses 90 90 15 15 45 45 30 30
The width of the rectangle can be found by using the formula for the perimeter of a rectangle: P = 2(length + width).
Given that the length is 15 and the perimeter is 90, 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:
30 = width.
So, the width of the rectangle is 30.
To find the width of a rectangle, we can use the formula for the perimeter:
Perimeter = 2 × (Length + Width)
Given:
Perimeter = 90
Length = 15
Substituting the values into the formula, we get:
90 = 2 × (15 + Width)
Divide both sides of the equation by 2:
45 = 15 + Width
Subtract 15 from both sides of the equation:
45 - 15 = Width
Therefore, the width of the rectangle is 30.
To find the width of a rectangle, we need to know its perimeter and length.
A rectangle's perimeter can be calculated by adding the lengths of all four sides. In this case, the perimeter is given as 90.
Since the length is given as 15, the equation to find the width can be set up as follows:
Perimeter = 2 * (Length + Width)
90 = 2 * (15 + Width)
To solve for the width, we can start by dividing both sides of the equation by 2:
90/2 = (15 + Width)
45 = 15 + Width
Now, to isolate the width, we subtract 15 from both sides of the equation:
45 - 15 = Width
30 = Width
Therefore, the width of the rectangle is 30.
