For items 1 to 4. Area of a square is defined as the number of square units needed to fill a square. In general, the area is defined as the region occupied inside the boundary of a flat object. While measuring the area of a square, we consider only the length of its side. All sides of a square are equal; hence, its area is equal to the square of the side. 1. If a square garden has an area of 144 square meters. What is the length of a side of the square garden?

• 11
• 12

If the side length is 12 meters, what is the perimeter of the garden?

• 36 meters
• 48 meters
• 36 square meters
• 48 square meaters

The area of another square garden is four times larger than the previous one. What is the side length of the larger garden?

• 14 meters
• 20 meters
• 22 meters
• 24 meters

While measuring the area of a square, we consider only the length of its side. All sides of a square are equal; hence, its area is equal to the square of the side. 4. If the area of the garden is doubled, will its side length also double? Explain your reasoning.

• a. Yes, the side length doubles because the relationship between area and side length is linear.
• b. Yes, the side length will double because doubling the area directly doubles the side length.
• c. No, doubling the area does not change the side length because the side length depends only on the original area.
• d. No, the side length will increase, but it will not double. It will increase by the square root of 2 times the original side length.

5. You are given the equation n2 = 121. Solve for n.

• a. 10
• b. 11
• c. 12
• d. 13
