Stretch Worksheet on Area & Perimeter

Hi 4A,

This post is for Question 1 of our Area & Perimeter Stretch Worksheet.

Method 1 solution :

To visualise by removing  the concrete path and rejoining the remaining park.

Hence the length became : 30m - 3m = 27m

Area  covered by grass =  Length x Breadth
                                      =   30 m x 27 m
                                        = 540 square metres 

Some of you came up with the alternative solution of finding the area of the concrete path.

Method 2 solution: 

 Area of concrete path = 3 x 20 = 60 square metres
Area of Park = 30 x 20 = 600 square metres
Area covered by grass = 600 - 60 = 540 square metres

For this solution , we need to find the area of 2 parallelograms first ( which is also Length x breadth)
