Question

15. The area of a rectangular field is 456m2 and its length is 24m find the breadth and
perimeter of the field.​

Answer 1

area of rectangle = length × breadth = l×b=24b

456m² = 24b

b= 456/24 = 19meter

breadth is 19m

Answer 2

Given :

• Area of Rectangular field is 456 m² .
• Length of field is 24 m .

To Find :

• Perimeter of Field .

Solution :

Firstly we will find Breadth of Field :

$\longmapsto\tt{Length=24\:m}$

Using Formula :

$\longmapsto\tt\boxed{Area\:of\:Rectangle=l\times{b}}$

Putting Values :

$\longmapsto\tt{456=24\times{b}}$

$\longmapsto\tt{\cancel\dfrac{456}{24}=b}$

$\longmapsto\tt\bf{19\:m=b}$

Now ,

$\longmapsto\tt{Length=24\:m}$

$\longmapsto\tt{Breadth=19\:m}$

Using Formula :

$\longmapsto\tt\boxed{Perimeter\:of\:Rectangle=2(l+b)}$

Putting Values :

$\longmapsto\tt{2(24+19)}$

$\longmapsto\tt{2(43)}$

$\longmapsto\tt\bf{86\:m}$

So , The Perimeter of Rectangle is 86 m..
