48. since the perimeter of something is all of the sides added up, you take the length(14) and multiply it by 2 because you have 2 sides. this adds up to 28. then you take the width(10) and mutiply that by 2 because you have 2 sides. this is 20. you then take your first sum(28) and add it to your second sum(20). this equals 48
The length is (18 centimeters) minus (the width)
77cm!
Perimeter of rectangle = 2 x (Length + Width) = 2 x (L + 18) or = (2L + 36) centimetres.
3 cm
Another Answer:The length of the rectangle is 29 cm because 2*(29+23) = 104 cm which is the perimeter
