A rectangle is 21 meters long and 11 meters wide. What is the perimeter of this rectangle?

32 m

42 m

64 m

84 m

P = 64 meters

Step-by-step explanation:

P = 2(l+w) for a rectangle

Substitute in the length and the width

P = 2( 21+11)

P = 2( 32)

P = 64 meters

P = 2(l+w)

= 2 ( 21+11)

= 2(32)

= 64m

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
