Question

$\begin{array}{cc}ColumnA& ColumnB\\ 1.\text{Area}& \text{a. 67 m}\\ 2.\text{Perimeter}& {\text{b. Rs.6/m}}^2\\ 3.\text{Cost per}{m}^2& {\text{c. 100 m}}^2\\ & d.Rs.{\text{6 m}}^2\\ & {\text{e. 100/m}}^2\end{array}$

Which of the following options show the correct match of parameters in column A with possible values in column B?

• A. 1-d ; 2-a ; 3-b
• B. 1-c ; 2-a ; 3-d
• C. 1-c ; 2-a ; 3- b
• D. 1-c ; 2-e ; 3- d

Answer 1

The correct option is C

1-c ; 2-a ; 3- b

The unit of Area is the square of the unit of length. Hence, in this case, it is $m^2$

The unit of perimeter is the unit of length. It is m

Cost per unit area has a unit of $Rs/m^2$
