6) What is the perimeter of a rectangle with length 13 and width 10?

23 units

130 units

46 units

33 units

None of the above

The perimeter of a rectangle is calculated by adding up all four sides of the rectangle. In this case, the length of the rectangle is 13 units and the width is 10 units. To find the perimeter, we add twice the length and twice the width: 2(13) + 2(10) = 26 + 20 = 46 units. Therefore, the correct answer is 46 units.

Explanation

The perimeter of a rectangle is calculated by adding up all four sides of the rectangle. In this case, the length of the rectangle is 13 units and the width is 10 units. To find the perimeter, we add twice the length and twice the width: 2(13) + 2(10) = 26 + 20 = 46 units. Therefore, the correct answer is 46 units.

8) What is the area of this parallelogram?

16 cm²

28 cm²

19 cm²

32 cm²

The area of a parallelogram is calculated by multiplying the base length by the height. Since the question does not provide the measurements of either the base or the height, it is not possible to determine the area of the parallelogram. Therefore, an explanation for the correct answer of 32 cm² is not available.

Explanation

The area of a parallelogram is calculated by multiplying the base length by the height. Since the question does not provide the measurements of either the base or the height, it is not possible to determine the area of the parallelogram. Therefore, an explanation for the correct answer of 32 cm² is not available.

9) What is the perimeter of this rectangle?

The area of a rectangle is given by the formula A = l * w, where A is the area, l is the length, and w is the width.

In this case, the area is 60 cm² and the width is 6 cm. We can use the formula to find the length:

l = A / w = 60 cm² / 6 cm = 10 cm

The perimeter of a rectangle is given by the formula P = 2(l + w), where P is the perimeter, l is the length, and w is the width.

Substituting the values we found, we get:

P = 2(10 cm + 6 cm) = 2(16 cm) = 32 cm

Explanation

The area of a rectangle is given by the formula A = l * w, where A is the area, l is the length, and w is the width.

In this case, the area is 60 cm² and the width is 6 cm. We can use the formula to find the length:

l = A / w = 60 cm² / 6 cm = 10 cm

The perimeter of a rectangle is given by the formula P = 2(l + w), where P is the perimeter, l is the length, and w is the width.

Substituting the values we found, we get:

P = 2(10 cm + 6 cm) = 2(16 cm) = 32 cm
