Week 320 (27th October 2023)

A group of friends are planning a Halloween party. 

They want to create a haunted maze in a field near where they live. 

The maze will be a rectangular shape with a length of 40m and a width of 30m.  

They want to place fake spiderwebs every 2m along the perimeter of the maze.  

How many fake spiderwebs will they need to buy for the entire maze? 


Perimeter = 2(length + width) = 2(30+40) = 140m 

To find the number of spider webs needed we can divide the perimeter by the distance between the webs.  

Number of spider webs = 140/2 = 70 spider webs.
