2. A school allocated RM15000 for the cost of installing tiles to an area measuring 20m ×25m. If the tiles cost RM36 per m^2, do they have enough money?
1. The height of Tower A is 350 m whereas the height of a scale drawing of Tower A is 14 cm. State the scale used.
1. We need to convert the height of Tower A to cm unit. 350 m = 35000 cm.
The scale is 14 : 35000 = 1 : 2500
So the scale used is 1 : 2500
2. From the question above, we can find the area is 20 m x 25 m = 500 m²
Because of the tiles cost is RM36/m², so they must spend RM18000.
We can conclude that they don't have enough money.
