Question

A 15 wide rectangular hall has floor area 195 2. Find its perimeter.

Answer 1

Answer:

56

Step-by-step explanation:

length×breath=area

length×15=195

length=195/15

length=13

perimeter=2(l+b)

=2(13+15)

=2(28)

=56

Answer 2

GIVEN TO SOLVE :-

Perimeter of the rectangular hall.

GIVEN USEFUL HINTS :-

Length = x units

Breadth = 15 units

Area Of Rectangular Hall = 195 square units

SOLVATION :-

We Know That,

Area of rectangle = Length X Breadth

By Substituting Values,

$195 = x \times 15$

$x \times 15 = 195$

$x = \frac{195}{15}$

$x = 13$

Therefore, Length = 13 Units

We Have To Find Perimeter Of Rectangle.

Perimeter Of Rectangle = 2 ( Length + Breadth )

By Substituting Values,

Perimeter of rectangle

$= 2(15 + 13)$

$= 2(28)$

$= 56$

CONCLUSION :-

The Perimeter Of Rectangle = 56 units.

USED FORMULAE :-

Area of rectangle = Length X Breadth

Perimeter Of Rectangle = 2 ( Length + Breadth )
