Area and Perimeter Challenges: Circles and Quadrilaterals

A rectangular garden measures 10 meters in length and 5 meters in width. What is the area of the garden?

• 40 square meters

• 50 square meters

• 30 square meters

• 25 square meters

If the same garden has a fence around it, what is the perimeter of the garden?

• The perimeter is always 100 meters.

• The perimeter is the same as the area.

• The perimeter can be calculated without knowing the dimensions.

• The perimeter of the garden depends on its dimensions.

A circular pond has a radius of 3 meters. What is the area of the pond?

• 12π square meters

• 3π square meters

• 9π square meters

• 6π square meters

What is the circumference of the circular pond with a radius of 3 meters?

• 9.42 meters

• 12.56 meters

• 25.13 meters

• 18.85 meters

A triangle has a base of 8 cm and a height of 5 cm. What is the area of the triangle?

• 15 cm²

• 25 cm²

• 30 cm²

• 20 cm²

If the triangle is placed inside a rectangle with the same base and height, what is the area of the rectangle?

• Area = (base × height) / 2

• Area = base × height

• Area = base - height

• Area = base + height

A square park has a side length of 12 meters. What is the area of the park?

• 144 square meters

• 120 square meters

• 100 square meters

• 1440 square meters

What is the perimeter of the square park?

• P = 4 * (side_length + 1)

• P = 4 * side_length

• P = side_length^2

• P = 2 * (length + width)

A circular track has a diameter of 20 meters. What is the area of the track?

• 100π square meters

• 25π square meters

• 200 square meters

• 50π square meters

If you walk around the circular track, what distance do you cover (circumference)?

• C = π * d

• C = 2 * r

• C = 2 * π * r

• C = π * r^2
