Question

The area of room is 65 1/4 sq.m. if its lenth is 12 meter find its breadth

Answer 1

area=261/4

length=12

breadth=??

area of room = length*breadth

261/4=12*b

therefore

b=261/48

b=5.43

Answer 2

$\underline{\mathfrak{\huge{The\:Question\:is:}}}$

The Area of a room is $\tt{65\frac{1}{4} m^{2}}$. The length given is equal to 12 metres. Find the breadth of the same room.

$\underline{\mathfrak{\huge{Here's \:Your\:Answer:}}}$

Let the breadth ( which is the value we need to find ) be equal to x

The Area of a rectangle ( or a rectangular room ) is the value we get after multiplying its length and breadth. This, in a form of a formula can be represented as:

Area of a rectangle = Length × Breadth

Put the given values in the formula and then solve it. The Given values are :

Area = $\tt{65\frac{1}{4} m^{2}}$ = $\tt{\frac{261}{4} m^{2}}$

Length = 12 m

Put these value in the formula and then solve it:

=》 $\tt{\frac{261}{4} = 12x}$

=》 $\tt{65.25 = 12x}$

=》 $\tt{x = 5.4375}$m

The breadth will be equal to 5.4375 m.

The explanation I wrote in this answer isn't compulsory to even write in the examinations. You may simply write the given values, the formula, and then do simple derivation of the answer.
