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:

length=15m

Perimeter=46

Step-by-step explanation:

Given,

Area=120m

Breadth=8m

Area of a rectangle=l×b

=l×8=120

l=120÷8

l=15

Perimeter=2×[l+b]

=2×[15+8]

=2×23

=46

Answer 2

Given :

• Area of Rectangle is 120 m² .
• Breadth is 8 m .

To Find :

• Length and Perimeter of Rectangle .

Solution :

For Length of Rectangle :

Using Formula :

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

Putting Values :

$\longmapsto\tt{120=l\times{8}}$

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

$\longmapsto\tt\bf{15\:m=l}$

Now ,

For Perimeter :

Using Formula :

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

Putting Values :

$\longmapsto\tt{2(15+8)}$

$\longmapsto\tt{2(23)}$

$\longmapsto\tt\bf{46\:m}$

So , The Perimeter of Rectangle is 46 m .
