What is the perimeter, P, of a rectangle that has a length of x + 5 and a width of y − 1
The perimeter of a rectangle is given by the formula P = 2(l + w), where l is the length and w is the width. Substituting the given values, we get:
P = 2(x + 5 + y - 1)
Simplifying the expression, we get:
P = 2x + 2y + 8
Therefore, the perimeter of the rectangle is 2x + 2y + 8.
To find the perimeter, P, of a rectangle, we need to add up all the sides. A rectangle has two pairs of equal sides.
The length of the rectangle is x + 5, so we have two sides with this length.
The width of the rectangle is y - 1, so we have two sides with this length.
To find the perimeter, we can add up all the sides:
P = (x + 5) + (x + 5) + (y - 1) + (y - 1)
Simplifying the equation:
P = 2x + 10 + 2y - 2
Finally, we can combine like terms:
P = 2x + 2y + 8
Therefore, the perimeter, P, of the rectangle is 2x + 2y + 8.
