In today's maths lesson with Múinteoir John, we learned how to measure area. This is an important skill to have.  

Take a look at your floor. It may be covered in carpet or tiles or wood. But how do you know how much carpet you need to cover the entire floor?  

Well, you measure the area and that tells exactly how much carpet you need to buy!  

It's like a fun jigsaw but you can now use maths to solve it!  

Quick recap!  

Perimeter is the distance around the outside of a shape. 

Area measures the space inside a shape. We measure area in metres squared which is written as m²  

The formula for area is Length x Width = m²

Wow! You just got hired to protect the pitch at Croke Park. Unfortunately, the goal area of the pitch has been damaged by all the matches.  

The Dublin players have been scoring too many goals! (Múinteoir John made us say that!)

You must buy a cover to protect the goal area but how much do you need? It's expensive so you need to measure the area! 

1) Calculate the area you need to protect using the measurements above. What is the square area? 

2) The cost of the cover is €3 per square metre. How much will your cover cost? 

Check answers at the bottom of your worksheet.

Look carefully at the nine pictures. They all look different but if you closer, you will see only one is unique. Can you find the one of a kind? 

Hint: 1 and 7 are identical.

Some jokes for you...

Q. What did 0 say to 8?  

A. Nice belt!  

Q. Are monsters good at math? 

A. Not unless you Count Dracula 

Q. Why was 6 afraid of 7?  

A. Because 7, 8, 9!  

ANSWERS 

1) The area of the goal is 75m² 

2) The cost of the cover is 75 x 3 which is €225. Congratulations, you saved Croke Park!

8 is the odd one out.  

2 and 4 are identical. 3, 5 and 7 are also identical.
