• A. $\text{Rs.}160$
• B. $\text{Rs.}200$
• C. $\text{Rs.}220$
• D. $\text{Rs.}240$

Answer 1

The correct option is D $\text{Rs.}240$

The given floor is rectangular with length$\left(l\right)=12$ feet and breadth $\left(b\right)=8$ feet

Area of the rectangular floor$=l\times b$

$=12\times 8$

$=96$ sq. feet

Given $\text{Rs.}2.50$ is the cost of the materials per square foot.

$\therefore$ Cost of materials for $96$ sq. feet

$=96\times 2.50$

$=\text{Rs.}240.0$
