Work out the length and breadth of each rectangle and 2. Change the sizes of the rectangles in the following ways: a. reduce to 50% of the original size b. reduce to 1/3 of the original size c. enlarge to 200% of the original size d. enlarge to 150% of the original size.

Okay, Kaido, let's tackle this resizing problem.

To answer question 1, I need to see page 97, which contains the rectangles you need to count. Please send a photo of that page if you'd like me to help with question 1.

For question 2, I will explain how to calculate the new dimensions. You will need to substitute the original length and breadth from question 1 into these formulas. Let's assume the original length is $L$ and the original breadth is $B$.

2. Change the sizes of the rectangles in the following ways:

   • a) reduce to 50% of the original size To reduce to 50%, multiply the original dimensions by 0.5 (or $\frac{1}{2}$).

     $$\text{New Length} = L \times 0.5$$ $$\text{New Breadth} = B \times 0.5$$

   • b) reduce to $\frac{1}{3}$ of the original size To reduce to $\frac{1}{3}$, multiply the original dimensions by $\frac{1}{3}$.

     $$\text{New Length} = L \times \frac{1}{3}$$ $$\text{New Breadth} = B \times \frac{1}{3}$$

   • c) enlarge to 200% of the original size To enlarge to 200%, multiply the original dimensions by 2.

     $$\text{New Length} = L \times 2$$ $$\text{New Breadth} = B \times 2$$

   • d) enlarge to 150% of the original size To enlarge to 150%, multiply the original dimensions by 1.5 (or $\frac{3}{2}$).

     $$\text{New Length} = L \times 1.5$$ $$\text{New Breadth} = B \times 1.5$$
