Question

The length of a rectangle is $12$ m and its area is $72m^2$. Then the breadth equals to

• A. $72$ m
• B. $60$ m
• C. $6$ m
• D. $9$ m

Answer 1

Answer: (C)

$6$ m

Let $l,b$ and $A$ are length, breadth and area of the rectangle respectively.
Then given , $l=12$ m, $A=72$ sq.m
Now we know, area of rectangle $=lb$
$\Rightarrow 12b=72$

$\Rightarrow b=\frac{72}{12}=6$ m
Hence, breadth of the given rectangle is $6$ m.
