A rectangle has a length x centimeters and a width that is equal to half its length. The perimeter of the rectangle is 50 centim etres. What is the length and width of the rectangle?
2 answers:
The length is 18 cm and the width is 9cm
Answer:
Step-by-step explanation:
Let x = length
Then width = (1/2)x
Perimeter = 2(length) + 2(width) = 54
length + width = 27
So, x + (1/2)x = 27
(3/2)x = 27
x = 27(2/3) = 18 (1/2)x = 9
Answer: length = 18 cm and width = 9 cm
