• 150 square units

• 100 square units

What is the area of a rectangle with dimensions 8 units by 10 units?

• 60 square units

• 70 square units

• 80 square units

• 90 square units

How do you find the area of a triangle with a height of 4 mm and a base of 6 mm?

• Area = 1/2 × base × height = 1/2 × 6 × 4 = 12 mm²

• Area = base × height = 6 × 4 = 24 mm²

• Area = 1/2 × base × height = 1/2 × 4 × 6 = 12 mm²

• Area = 1/2 × (base + height) = 1/2 × (6 + 4) = 5 mm²

If a triangle has a base of 8 cm and a height of 3 cm, what is its area?

• 10 cm²

• 12 cm²

• 14 cm²

• 15 cm²

How do you calculate the area of a rectangle?

• Area = length + width.

• Area = length × width.

• Area = length - width.

• Area = length ÷ width.

What is the formula for finding the area of a rhombus?

• Area = (side × side)

• Area = (base × height)

• Area = (diagonal1 × diagonal2) / 2.

• Area = (perimeter × apothem) / 2.

What is the definition of a quadrilateral?

• A polygon with three sides.

• A polygon with four sides.

• A polygon with five sides.

• A polygon with six sides.

If the area of a rectangle is 72 square units and one side is 9 units, what is the other side?

What is the formula to find the area of a triangle?

• A = 1/2 bh, where A is the area, b is the base, and h is the height.

• A = b + h, where A is the area, b is the base, and h is the height.

• A = b * h, where A is the area, b is the base, and h is the height.

• A = 2bh, where A is the area, b is the base, and h is the height.

What is the formula for the area of a trapezoid?

• Area = base × height

• Area = 1/2 × (base1 + base2) × height

• Area = (base1 + base2) × height

• Area = 1/2 × (base1 - base2) × height
