What is the cost of tiling a rectangular plot of land 500 m long and 200 m wide at the rate of ` 8 per hundred sq m? TIPS Firstly, find the area of a rectangular plot. Then, to find the required cost, multiply the area by rate of tiling i.e.\[\frac{8}{100}.\] [\[\because \]rate = ` 8 per hundred sq m]

Answer:

Given, length of a rectangular plot = 500 m and breadth of a rectangular plot = 200 m \[\therefore \]Area of the rectangular plot = Length \[\times \] Breadth \[=500m\times 200m=100000sqm\] \[\because \]Cost of tiling per hundred square metres = ` 8 \[\therefore \] Cost of one sq metre = ` \[\frac{8}{100}\] Now, cost of 100000 sq metre = ` \[10000\times \frac{8}{100}=\] ` 8000 Hence, the cost of tiling rectangular plot is ` 8000.
