Answer:
C). 54 cm.
Step-by-step explanation:
I think you mean a rectangle .
If the length is x then the width = 0.75x (because 3/4 = 0.75).
Perimeter = 2*length + 2*width.
252 = 2x + 2*0.75x
252 = 2x + 1.5x
252 = 3.5x
x = 252 / 3.5
= 72 which is the length,
The width = 3/4 * 72
= 54 cm.
The perimeter of the rectangle is 120

Answer:
The ratio in which the amount is shared is 16:19:13
Step-by-step explanation:
The given parameters are;
The number of days Henry worked = 8 days
The number of days Jack worked = 9.5 days
The number of days Steffi worked = 6.5 days
The sharing formula for the amount earned for the project = The ratio of the number of days worked by each one
The total number of days worked by all three = 8 days + 9.5 days + 6.5 days = 24 days
The fraction of the total number of days Henry worked = (8 days)/(24 days) = 1/3 = 16/48
The fraction of the total number of days Jack worked = (9.5 days)/(24 days) = 19/48
The fraction of the total number of days Steffi worked = (6.5 days)/(24 days) = 13/48
Therefore. the ratio in which the amount is shared = 16:19:13 (which is the same as the ratio of the number of days worked)
