Question

Given alongside is the diagram of a playground. It shows the length of its sides. Find the perimeter of the playground.

Answer 1

Side AF = side BC + side DE 

∴ Side AF = 15 + 15 = 30 m 

Side FE = side AB + side CD 

∴ Side FE = 10 + 5 = 15 m 

∴ Perimeter of the playground = side AB + side BC + side CD + side DE + side FE + side AF 

= 10 + 15 + 5 + 15 + 15 + 30 

= 90 m. 

∴ The perimeter of the playground is 90 m.
