$11
$12

hint Hint:

To find the cost of 1 meter cloth we will divide cost of $7 over 2 m$ by $7 over 2 m$ .

The correct answer is: $33

STEP BY STEP SOLUTION
Cost of $7 over 2 space m$ cloth = $ $231 over 4$
Cost of 1 meter cloth = $fraction numerator C o s t space o f space begin display style 7 over 2 end style m space c l o t h space over denominator begin display style 7 over 2 end style m end fraction$
$231 over 4 space divided by space 7 over 2 space equals space 231 over 2 space cross times space 2 over 7 space equals space 462 over 14 space equals space 33$
Cost of 1 meter cloth = $33
