How many squares 5cm x 5cm can you cut from a card 20cm x 40cm?
To determine how many 5cm x 5cm squares can be cut from a 20cm x 40cm card, first calculate the area of the card, which is 20cm x 40cm = 800cm². The area of one square is 5cm x 5cm = 25cm². Dividing the area of the card by the area of one square, 800cm² ÷ 25cm², gives you 32 squares.
If the dimensions of a 20cm x 40cm rectangle are each reduced 20. by what percent is the area of 20cm x 40cm rectangle reduced?
The original area of the rectangle is 20 cm × 40 cm = 800 cm². When each dimension is reduced by 20%, the new dimensions become 16 cm (20 cm - 20% of 20 cm) and 32 cm (40 cm - 20% of 40 cm), giving a new area of 16 cm × 32 cm = 512 cm². The reduction in area is 800 cm² - 512 cm² = 288 cm². To find the percentage reduction, divide the area reduction by the original area: (288 cm² / 800 cm²) × 100% = 36%. Thus, the area is reduced by 36%.

What is the area of a regular hexagon with side length of 40cm?
To find the area of a regular hexagon with side length of 40cm, consider that since it is regular, then it consists of 6 equilateral triangles of side 40cm. Half of each of those triangles is a right triangle. By the pythagorean theorem, we know that if the hypotenuse is 40cm, and one side is 20cm, then the other side is the square root of (40cm squared - 20cm squared) or about 34.64cm. That makes the area of each of those 12 right triangle to be about 692.8cm, so the total area of the hexagon is about 8313.8cm.
