Read each question carefully and calculate the area of the regular polygons. Show all your work.
1. Find the area of an equilateral triangle with a side length of 6 cm.
2. If a square has a side length of 8 inches, its area is square inches.
3. A regular hexagon has a side length of 4 cm. What is its area, rounded to two decimal places? (Formula: Area = (3√3/2) * s²)
41.57 cm²
24.00 cm²
36.00 cm²
16.00 cm²
4. A regular pentagon has an apothem of 5 cm and a side length of 7.27 cm. Calculate its area. (Formula: Area = (1/2) * apothem * perimeter)
5. The formula for the area of any regular polygon is (1/2) * apothem * perimeter.
