Maths Mate Term 4 Sheet 8 (finally!) Question 23

Predict: I predict that this question will be about addition.

Read: A square has a perimeter of 60 cm. A rectangle has the shape of two of these squares placed side by side. What is the perimeter of the rectangle?

Clarify: I had nothing to clarify in this question.

Mathematician’s Toolbox: The strategy I used from the mathematician’s toolbox was to use prior knowledge.

Big question: The big question is what is the perimeter of the rectangle.

Solve: Firstly, I knew that by putting the squares side by side, one of their sides will be gone, and squares have 4 sides. So then I divided 60 by 4, and that was 15. I took away 15 from 60, which was 45, and then added 45 and 45. This was 90, and that is the answer.

Summary: This problem was easy to solve, and there is NO MORE MATHS MATE! HOORAY! Bye!
