1. What is the formula for calculating the area of a rectangle?
- The formula for calculating the area of a rectangle is length x width.
2. What is the formula for calculating the perimeter of a rectangle?
- The formula for calculating the perimeter of a rectangle is 2(length + width).
3. Calculate the area of a rectangle with a length of 5 cm and a width of 8 cm.
- Area = length x width
- Area = 5 cm x 8 cm
- Area = 40 square cm
4. Calculate the perimeter of a rectangle with a length of 10 cm and a width of 6 cm.
- Perimeter = 2(length + width)
- Perimeter = 2(10 cm + 6 cm)
- Perimeter = 2(16 cm)
- Perimeter = 32 cm
5. Determine the dimensions of a rectangle whose area is 24 square meters and the perimeter is 20 meters.
- Let the length of the rectangle be x meters and the width be y meters.
- Area = x*y = 24 square meters
- Perimeter = 2(x + y) = 20 meters
- Solving these two equations simultaneously, we get x = 4 meters and y = 6 meters. Therefore, the dimensions of the rectangle are 4 meters by 6 meters.
