A rectangle of length y m and breadth 4 m less than the length. What is the perimeter??
P = 2L + 2W
P = 2y + 2(y-4)
P = 4y - 8
God bless you
To find the perimeter of the rectangle, we need to add up the lengths of all four sides.
Given:
Length of the rectangle = y meters
Breadth of the rectangle = length - 4 meters = y - 4 meters
Perimeter of the rectangle = 2(Length + Breadth)
Substituting the given values, we get:
Perimeter = 2(y + y -4)
Simplifying this expression:
Perimeter = 2(2y - 4)
Perimeter = 4y - 8
Therefore, the perimeter of the rectangle is 4y - 8 meters.
To find the perimeter of a rectangle, we add the lengths of all four sides.
Let's break down the information given:
Length of the rectangle = y meters
Breadth of the rectangle = 4 meters less than the length = (y - 4) meters
The perimeter of a rectangle is given by the formula:
Perimeter = 2 * (Length + Breadth)
Substituting the values we have:
Perimeter = 2 * (y + (y - 4))
Simplifying the expression:
Perimeter = 2 * (2y - 4)
Perimeter = 4y - 8
Therefore, the perimeter of the rectangle is 4y - 8 meters.
