Question

the area of rectangle is 120 metre square and its breadth is 8 m . find the length of the rectangle and perimeter of the rectangle ?!

​

Answer 1

Answer:

46 m

Step-by-step explanation:

Area of Rectangle is 120 m² .

Breadth is 8 m .

To Find :

Length and Perimeter of Rectangle .

Solution :

For Length of Rectangle :

Using Formula :

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

AreaofRectangle=l×b

Putting Values :

\longmapsto\tt{120=l\times{8}}⟼120=l×8

\longmapsto\tt{\cancel\dfrac{120}{8}=l}⟼

8

120

=l

\longmapsto\tt\bf{15\:m=l}⟼15m=l

Now ,

For Perimeter :

Using Formula :

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

PerimeterofRectangle=2(l+b)

Putting Values :

\longmapsto\tt{2(15+8)}⟼2(15+8)

\longmapsto\tt{2(23)}⟼2(23)

\longmapsto\tt\bf{46\:m}⟼46m

So , The Perimeter of Rectangle is 46 m .

Answer 2

Answer:

Thanks for thanking dear

Have a bangtastic day❤❤

Given:

Area of the rectangle = 120 m

Breadth of the rectangle = 8 m

To find: Here we have to find the length of the rectangle and perimeter of the rectangle.

Solution:

We know that:

Area of rectangle = Length Breadth

Also, given that;

Area of the rectangle = 120 m2

So,

Length Breadth = 120 m2

Length 8 m = 120 m2

Length 8 m = 120 m2

Length =

m

Length = 15 m

Now,

Perimeter = 2(Length Breadth)

Perimeter = 2(15 8)

Perimeter = 2(23)

Perimeter = 46 m

So, length of the rectangle is 15 m and Perimeter is 46 m.
