We were assigned textbook questions from Chapter 2.3 and 2.4.
The question that I will be telling you about is question15 from chapter 2.4 on page 79.
The question is "Kai needs to replace the strip of laminate that is glued to the vertical faces on a square tabletop. The tabletop has an area of 1.69 squared metres. What is the length of laminate does she need?"
I solved this question easily by finding the square root of 1.69 squared metres.
Since the tabletop is square, finding the square root would be perfect.
Why, you may ask. Well, to get rid of the "squared" part and the square root of 1.69 is 1.3.
1.3 x 1.3 = 1.69
Kai needs a laminate with the length of 1.3 to replace the old laminate.
Sorry there are no pictures or colour. It still will not let me.
