Answer:
180 ft
Step-by-step explanation:
We are working to find the perimeter here. Let x represent the length of the room.
We know that the formula to find the perimeter of something is 2L + 2W = P. Here, we know the required perimeter and the width of the room.
Our equation is now: 2x + 2(70) = 500
Now we have to find x, we'll start by multiplying 70 by 2.
2x + 140 = 500
Now we can solve for x:
Subtract 140 from both sides
2x = 360
x = 180
The length of this room is 180 ft.
2(180) + 140 = 500
360 + 140 = 500
Answer:

Step-by-step explanation:
Answer:
The perimeter of the playground is 65 metres
Step-by-step explanation:
Questions like this requires attachment; See attachment for diagram.
From the diagram, we have the following parameters


Required
Calculate the parameter of the actual diagram
First, the actual length and width has to be calculated;
Given that the scale drawing is 1:500


Now, the perimeter can be calculated;




However, the question requires answer to be in meters
If 100 cm = 1 m, then


Hence, the perimeter of the playground is 65 metres
The copy machine makes 105 copies per minutes.
Step-by-step explanation:
Given,
Copies printed by photocopy machine = 735
Time taken by machine = 7 minutes
To find the unit rate in terms of minutes, we will divide the copies printed by machine by the time taken.
Copies printed in one minute = 
Copies printed in one minute = 105 copies
The copy machine makes 105 copies per minutes.
