A rectangular room is 15 ft long and 10 ft wide. How many square feet of carpet are needed to cover the floor?
Answer: 150 ft²
Area = length × width = 15 × 10 = 150 ft².

A parallelogram has a base of 10 m and a height of 4 m. What is its area?
Answer: 40 m²
Area of a parallelogram = base × height = 10 × 4 = 40 m².
Which of the following is NOT a property of a rectangle?
Answer: All four sides are equal in length
Having all four sides equal is a property of a square (or rhombus), not a rectangle in general.
What is the measure of each interior angle of a regular hexagon?
Answer: 120°
Sum of interior angles of a hexagon = (6−2)×180° = 720°; each angle = 720° ÷ 6 = 120°.
A right triangle has legs of 5 cm and 12 cm. What is the length of the hypotenuse?
Answer: 13 cm
Using the Pythagorean theorem: 5² + 12² = 25 + 144 = 169, so hypotenuse = √169 = 13 cm.
