Calculating Land and Flag Areas: A Real-World Application

In this mathematical challenge, Mr. Khalid has a parallelogram-shaped plot of land measuring 168m by 70m, on which he plans to build a rectangular house of dimensions 35m by 25m. The primary task is to determine the area of the land that remains unoccupied after the house is built. Additionally, we look at a flag designed with black squares, calculating the area of the grey portion. Lastly, we will evaluate the costs of tiling a square hotel floor of 40m sides with smaller square tiles.

  2. Mr. Khalid has brought a plot of land which is in the shape of parallelogram with a base of 168m and a height of 70m. He wants to build a house with a rectangular base on the plot of land. The length of the house is 35m and the breadth is 25m. What is the area of the land that is not occupied by the house? Answer: • 5005 • 10535 • C. 10885 • D. 10987

  3. 2. Murugan drew a flag with 3 black squares on the grey rectangle. The length of the flag is 15cm and has a width is 8cm. Each black square has 2cm sides. Calculate the area of the flag which is grey. Answer: • 102 • 104 • 108 • 116

  4. 3. The floor of a hotel in the shape of square with sides of 40m is to be covered with square tiles of 20cm. If each tiles costs RM5.20, how much money is needed to tile the floor? Answer: • RM40000 • RM62500 • RM207895 • RM208000
