Question

What is the cost of tiling a rectangular plot of land 200 m long and 100 m wide at the rate of 0.01 per $m^2$ .

• A. $200
• B. $300
• C. $400
• D. $500

Answer 1

The correct option is A $200

Given,
Length of the rectangular plot of land = 200 m
Breadth of the rectangular plot of land = 100 m
Therefore, area of the rectangular plot
= length x breadth
= 200 m x 100 m
= 20000 m${}^2$

Given,
Cost of tiling per 1 $m^2$ of land = $ 0.01
We have,
Total cost of tiling = Cost of tiling per square metre x Total area of the land
So, cost of tiling 20000 $m^2$
= 0.01 x 20000
= $ 200
