A floor is paved with 500 identical parallelogram-shaped tiles. The base and corresponding height of each tile are 8 cm and 6 cm, respectively. What is the total area of the floor covered by the tiles (in cm²)?
24,000
Area of one parallelogram tile: \(\text{base}\times\text{height} = 8\times6 = 48\) sq cm.
Total area for 500 tiles: \(500\times48 = 24{,}000\) sq cm.
Hence, the total area of the floor covered by the tiles is 24,000 cm2.
The shorter side of a rectangle is 15 cm less than the longer side. The numerical value of its area is equal to 5 times the numerical value of its perimeter. What is the length (in cm) of its longer side?
