Answer:
The correct answer is perimeter is given by 2 × ( l + w), where l is the length and w is the width of the rectangle.
Explanation:
A rectangle has a length of 6 feet and a width of 4 feet. The perimeter of the rectangle can be found using the equation =2×6+2×4.
Let l be the length and w be the width of a rectangle.
Since there four sides of a rectangle, the perimeter is given by adding all the sides.
Therefore perimeter of the rectangle is given by l + l + b + b = 2×l +2×w = 2 × ( l + w).
The equation given by 2 × ( l + w) can also be used to find the perimeter of any given rectangle.
